According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Integer Overflow or Wraparound vulnerability in openEuler kernel on Linux (filesystem modules) allows     Forced Integer Overflow.This issue affects openEuler kernel: from 4.19.90 before 4.19.90-2401.3, from     5.10.0-60.18.0 before 5.10.0-183.0.0. (CVE-2021-33631)

  - An issue was discovered in drivers/input/input.c in the Linux kernel before 5.17.10. An attacker can cause     a denial of service (panic) because input_set_capability mishandles the situation in which an event code     falls outside of a bitmap. (CVE-2022-48619)

  - In the Linux kernel before 6.4.12, amdgpu_cs_wait_all_fences in drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c has     a fence use-after-free. (CVE-2023-51042)

  - In the Linux kernel before 6.4.5, drivers/gpu/drm/drm_atomic.c has a use-after-free during a race     condition between a nonblocking atomic commit and a driver unload. (CVE-2023-51043)

  - In the Linux kernel, the following vulnerability has been resolved: net: prevent mss overflow in     skb_segment() Once again syzbot is able to crash the kernel in skb_segment() [1] GSO_BY_FRAGS is a     forbidden value, but unfortunately the following computation in skb_segment() can reach it quite easily :
    mss = mss * partial_segs; 65535 = 3 * 5 * 17 * 257, so many initial values of mss can lead to a bad final     result. Make sure to limit segmentation so that the new mss value is smaller than GSO_BY_FRAGS.

  - In the Linux kernel, the following vulnerability has been resolved: uio: Fix use-after-free in uio_open     core-1 core-2 ------------------------------------------------------- uio_unregister_device uio_open idev     = idr_find() device_unregister(&idev->dev) put_device(&idev->dev) uio_device_release     get_device(&idev->dev) kfree(idev) uio_free_minor(minor) uio_release put_device(&idev->dev) kfree(idev)
    ------------------------------------------------------- In the core-1 uio_unregister_device(), the     device_unregister will kfree idev when the idev->dev kobject ref is 1. But after core-1 device_unregister,     put_device and before doing kfree, the core-2 may get_device. Then: 1. After core-1 kfree idev, the core-2     will do use-after-free for idev. 2. When core-2 do uio_release and put_device, the idev will be double     freed. To address this issue, we can get idev atomic & inc idev reference with minor_lock.
    (CVE-2023-52439)

  - In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix kernel NULL pointer     dereference in gfs2_rgrp_dump Syzkaller has reported a NULL pointer dereference when accessing rgd->rd_rgl     in gfs2_rgrp_dump(). This can happen when creating rgd->rd_gl fails in read_rindex_entry(). Add a NULL     pointer check in gfs2_rgrp_dump() to prevent that. (CVE-2023-52448)

  - An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4     (netfilter: nf_tables: Reject tables of unsupported family); While creating a new netfilter table, lack of     a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function enables an     attacker to achieve out-of-bounds access. (CVE-2023-6040)

  - An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue     may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that     results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).
    (CVE-2023-6121)

  - A Null pointer dereference problem was found in ida_free in lib/idr.c in the Linux Kernel. This issue may     allow an attacker using this library to cause a denial of service problem due to a missing check at a     function return. (CVE-2023-6915)

  - A memory leak problem was found in ctnetlink_create_conntrack in net/netfilter/nf_conntrack_netlink.c in     the Linux Kernel. This issue may allow a local attacker with CAP_NET_ADMIN privileges to cause a denial of     service (DoS) attack due to a refcount overflow. (CVE-2023-7192)

  - A vulnerability was found in vhost_new_msg in drivers/vhost/vhost.c in the Linux kernel, which does not     properly initialize memory in messages passed between virtual guests and the host operating system in the     vhost/vhost.c:vhost_new_msg() function. This issue can allow local privileged users to read some kernel     memory contents when reading from the /dev/vhost-net device file. (CVE-2024-0340)

  - An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in     the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy     length, leading to a denial of service. (CVE-2024-0565)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval()     function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes     are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every     iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local     user to cause a denial of service or potentially break NetFilter functionality. (CVE-2024-0607)

  - A denial of service vulnerability due to a deadlock was found in sctp_auto_asconf_init in     net/sctp/socket.c in the Linux kernel's SCTP subsystem. This flaw allows guests with local user privileges     to trigger a deadlock and potentially crash the system. (CVE-2024-0639)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error     within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when     NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit     f342de4e2f33e0e39165d8639387aa6c19dff660. (CVE-2024-1086)

  - In the Linux kernel, the following vulnerability has been resolved: tls: fix race between tx work     scheduling and socket close Similarly to previous commit, the submitting thread (recvmsg/sendmsg) may exit     as soon as the async crypto handler calls complete(). Reorder scheduling the work before calling     complete(). This seems more logical in the first place, as it's the inverse order of what the submitting     thread will do. (CVE-2024-26585)

  - In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum_acl_tcam: Fix NULL     pointer dereference in error path When calling mlxsw_sp_acl_tcam_region_destroy() from an error path after     failing to attach the region to an ACL group, we hit a NULL pointer dereference upon 'region->group->tcam'     [1].

  - When a router encounters an IPv6 packet too big to transmit to the next-hop, it returns an ICMP6 'Packet     Too Big' (PTB) message to the sender. The sender caches this updated Maximum Transmission Unit (MTU) so it     knows not to exceed this value when subsequently routing to the same host. (CVE-2023-52340)

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    In the Linux kernel, the following vulnerability has been resolved: ipv4, ipv6: Fix handling of     transhdrlen in __ip{,6}_append_data() Including the transhdrlen in length is a problem when the packet is     partially filled (e.g. something like send(MSG_MORE) happened previously) when appending to an IPv4 or     IPv6 packet as we don't want to repeat the transport header or account for it twice. This can happen under     some circumstances, such as splicing into an L2TP socket. The symptom observed is a warning in
    __ip6_append_data(): WARNING: CPU: 1 PID: 5042 at net/ipv6/ip6_output.c:1800
    __ip6_append_data.isra.0+0x1be8/0x47f0 net/ipv6/ip6_output.c:1800 that occurs when MSG_SPLICE_PAGES is     used to append more data to an already partially occupied skbuff. The warning occurs when 'copy' is larger     than the amount of data in the message iterator. This is because the requested length includes the     transport header length when it shouldn't. This can be triggered by, for example: sfd = socket(AF_INET6,     SOCK_DGRAM, IPPROTO_L2TP); bind(sfd, ...); // ::1 connect(sfd, ...); // ::1 port 7 send(sfd, buffer, 4100,     MSG_MORE); sendfile(sfd, dfd, NULL, 1024); Fix this by only adding transhdrlen into the length if the     write queue is empty in l2tp_ip6_sendmsg(), analogously to how UDP does things. l2tp_ip_sendmsg() looks     like it won't suffer from this problem as it builds the UDP packet itself.(CVE-2023-52527)

    In the Linux kernel, the following vulnerability has been resolved: binder: fix use-after-free in     shinker's callback The mmap read lock is used during the shrinker's callback, which means that using     alloc-vma pointer isn't safe as it can race with munmap(). As of commit dd2283f2605e ('mm: mmap: zap     pages with read mmap_sem in munmap') the mmap lock is downgraded after the vma has been isolated. I was     able to reproduce this issue by manually adding some delays and triggering page reclaiming through the     shrinker's debug sysfs.(CVE-2023-52438)

    A flaw in the routing table size was found in the ICMPv6 handling of  Packet Too Big . The size of the     routing table is regulated by periodic garbage collection. However, with  Packet Too Big Messages  it is     possible to exceed the routing table size and garbage collector threshold. A user located in the local     network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6     connections up to 95%.(CVE-2023-52340)

    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation.The nft_verdict_init() function allows positive values as drop error     within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when     NF_DROP is issued with a drop error which resembles NF_ACCEPT.(CVE-2024-1086)

    A null pointer dereference flaw was found in the hugetlbfs_fill_super function in the Linux kernel     hugetlbfs (HugeTLB pages) functionality. This issue may allow a local user to crash the system or     potentially escalate their privileges on the system.(CVE-2024-0841)

    In the Linux kernel before 6.4.5, drivers/gpu/drm/drm_atomic.c has a use-after-free during a race     condition between a nonblocking atomic commit and a driver unload.(CVE-2023-51043)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval()     function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes     are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every     iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local     user to cause a denial of service or potentially break NetFilter functionality.(CVE-2024-0607)

    A denial of service vulnerability due to a deadlock was found in sctp_auto_asconf_init in     net/sctp/socket.c in the Linux kernels SCTP subsystem. This flaw allows guests with local user     privileges to trigger a deadlock and potentially crash the system.(CVE-2024-0639)

    A Null pointer dereference problem was found in ida_free in lib/idr.c in the Linux Kernel. This issue may     allow an attacker using this library to cause a denial of service problem due to a missing check at a     function return.(CVE-2023-6915)

    Integer Overflow or Wraparound vulnerability in openEuler kernel on Linux (filesystem modules) allows     Forced Integer Overflow.This issue affects openEuler kernel: from 4.19.90 before 4.19.90-2401.3, from     5.10.0-60.18.0 before 5.10.0-183.0.0.(CVE-2021-33631)

    A denial of service vulnerability was found in tipc_crypto_key_revoke in net/tipc/crypto.c in the Linux     kernels TIPC subsystem. This flaw allows guests with local user privileges to trigger a deadlock and     potentially crash the system.(CVE-2024-0641)

    A use-after-free flaw was found in the Linux Kernel due to a race problem in the unix garbage collector's     deletion of SKB races with unix_stream_read_generic() on the socket that the SKB is queued     on.(CVE-2023-6531)

    An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4     (netfilter: nf_tables: Reject tables of unsupported family); While creating a new netfilter table, lack of     a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function enables an     attacker to achieve out-of-bounds access.(CVE-2023-6040)

    An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in     the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy     length, leading to a denial of service.(CVE-2024-0565)

    An issue was discovered in drivers/input/input.c in the Linux kernel before 5.17.10. An attacker can cause     a denial of service (panic) because input_set_capability mishandles the situation in which an event code     falls outside of a bitmap.(CVE-2022-48619)

    A vulnerability was found in vhost_new_msg in drivers/vhost/vhost.c in the Linux kernel, which does not     properly initialize memory in messages passed between virtual guests and the host operating system in the     vhost/vhost.c:vhost_new_msg() function. This issue can allow local privileged users to read some kernel     memory contents when reading from the /dev/vhost-net device file.(CVE-2024-0340)

    A memory leak problem was found in ctnetlink_create_conntrack in net/netfilter/nf_conntrack_netlink.c in     the Linux Kernel. This issue may allow a local attacker with CAP_NET_ADMIN privileges to cause a denial of     service (DoS) attack due to a refcount overflow.(CVE-2023-7192)

    A use-after-free flaw was found in the netfilter subsystem of the Linux kernel. If the catchall element is     garbage-collected when the pipapo set is removed, the element can be deactivated twice. This can cause a     use-after-free issue on an NFT_CHAIN object or NFT_OBJECT object, allowing a local unprivileged user with     CAP_NET_ADMIN capability to escalate their privileges on the system.(CVE-2024-0193)

    An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This flaw     allows a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that     results in kmalloc data to be printed (and potentially leaked) to the kernel ring buffer     (dmesg).(CVE-2023-6121)

    An out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux     Kernel. This issue could allow a local attacker to crash the system or leak internal kernel     information.(CVE-2023-6606)

    A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be     exploited to achieve local privilege escalation.A perf_event's read_size can overflow, leading to an heap     out-of-bounds increment or write in perf_read_group().(CVE-2023-6931)

Tenable has extracted the preceding description block directly from the EulerOS kernel security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-549 advisory.

    dm_table_create in drivers/md/dm-table.c in the Linux kernel through 6.7.4 can attempt to (in     alloc_targets) allocate more than INT_MAX bytes, and crash, because of a missing check for struct     dm_ioctl.target_count. (CVE-2023-52429)

    A flaw was found in the smb client in the Linux kernel. A potential out-of-bounds error was seen in the     smb2_parse_contexts() function. Validate offsets and lengths before dereferencing create contexts in     smb2_parse_contexts(). (CVE-2023-52434)

    In the Linux kernel, the following vulnerability has been resolved:

    net: prevent mss overflow in skb_segment()

    Once again syzbot is able to crash the kernel in skb_segment() [1]

    GSO_BY_FRAGS is a forbidden value, but unfortunately the followingcomputation in skb_segment() can reach     it quite easily :

    mss = mss * partial_segs;

    65535 = 3 * 5 * 17 * 257, so many initial values of mss can lead toa bad final result.

    Make sure to limit segmentation so that the new mss value is smallerthan GSO_BY_FRAGS.

    In the Linux kernel, the following vulnerability has been resolved:

    crypto: lib/mpi - Fix unexpected pointer access in mpi_ec_init (CVE-2023-52616)

    In the Linux kernel, the following vulnerability has been resolved:

    fs/ntfs3: Fix an NULL dereference bug (CVE-2023-52631)

    A vulnerability was found in vhost_new_msg in drivers/vhost/vhost.c in the Linux kernel, which does not     properly initialize memory in messages passed between virtual guests and the host operating system in the     vhost/vhost.c:vhost_new_msg() function. This issue can allow local privileged users to read some kernel     memory contents when reading from the /dev/vhost-net device file. (CVE-2024-0340)

    A null pointer dereference flaw was found in the hugetlbfs_fill_super function in the Linux kernel     hugetlbfs (HugeTLB pages) functionality. This issue may allow a local user to crash the system or     potentially escalate their privileges on the system. (CVE-2024-0841)

    A vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a     recursive operation of code push recursively calls into the code block. The OVS module does not validate     the stack depth, pushing too many frames and causing a stack overflow. As a result, this can lead to a     crash or other related issues. (CVE-2024-1151)

    A Speculative Race Condition (SRC) vulnerability that impacts modern CPU architectures supporting     speculative execution (related to Spectre V1) has been disclosed. An unauthenticated attacker can exploit     this vulnerability to disclose arbitrary data from the CPU using race conditions to access the speculative     executable code paths. (CVE-2024-2193)

    In btrfs_get_root_ref in fs/btrfs/disk-io.c in the Linux kernel through 6.7.1, there can be an assertion     failure and crash because a subvolume can be read out too soon after its root item is inserted upon     subvolume creation. (CVE-2024-23850)

    copy_params in drivers/md/dm-ioctl.c in the Linux kernel through 6.7.1 can attempt to allocate more than     INT_MAX bytes, and crash, because of a missing param_kernel->data_size check. This is related to     ctl_ioctl. (CVE-2024-23851)

    In the Linux kernel, the following vulnerability has been resolved:

    netfilter: nft_set_rbtree: skip end interval element from gc

    rbtree lazy gc on insert might collect an end interval element that hasbeen just added in this     transactions, skip end interval elements thatare not yet active. (CVE-2024-26581)

    In the Linux kernel, the following vulnerability has been resolved:

    net: tls: fix use-after-free with partial reads and async decrypt

    tls_decrypt_sg doesn't take a reference on the pages from clear_skb,so the put_page() in tls_decrypt_done     releases them, and we triggera use-after-free in process_rx_list when we try to read from thepartially-     read skb. (CVE-2024-26582)

    In the Linux kernel, the following vulnerability has been resolved:

    tls: fix race between async notify and socket close

    The submitting thread (one which called recvmsg/sendmsg)may exit as soon as the async crypto handler calls     complete()so any code past that point risks touching already freed data.

    Try to avoid the locking and extra flags altogether.Have the main thread hold an extra reference, this     waywe can depend solely on the atomic ref counter forsynchronization.

    Don't futz with reiniting the completion, either, we are nowtightly controlling when completion fires.
    (CVE-2024-26583)

    In the Linux kernel, the following vulnerability has been resolved:

    ext4: regenerate buddy after block freeing failed if under fc replay

    This mostly reverts commit 6bd97bf273bd (ext4: remove redundantmb_regenerate_buddy()) and reintroduces     mb_regenerate_buddy(). Based oncode in mb_free_blocks(), fast commit replay can end up marking as     freeblocks that are already marked as such. This causes corruption of thebuddy bitmap so we need to     regenerate it in that case. (CVE-2024-26601)

    In the Linux kernel, the following vulnerability has been resolved:

    sched/membarrier: reduce the ability to hammer on sys_membarrier

    On some systems, sys_membarrier can be very expensive, causing overallslowdowns for everything.  So put a     lock on the path in order toserialize the accesses to prevent the ability for this to be called attoo high     of a frequency and saturate the machine. (CVE-2024-26602)

    In the Linux kernel, the following vulnerability has been resolved:

    x86/fpu: Stop relying on userspace for info to fault in xsave buffer

    Before this change, the expected size of the user space buffer wastaken from fx_sw->xstate_size.
    fx_sw->xstate_size can be changedfrom user-space, so it is possible construct a sigreturn frame where:

    * fx_sw->xstate_size is smaller than the size required by valid bits infx_sw->xfeatures.* user-space     unmaps parts of the sigrame fpu buffer so that not all ofthe buffer required by xrstor is accessible.

    In this case, xrstor tries to restore and accesses the unmapped areawhich results in a fault. But     fault_in_readable succeeds because buf +fx_sw->xstate_size is within the still mapped area, so it goes     back andtries xrstor again. It will spin in this loop forever.

    Instead, fault in the maximum size which can be touched by XRSTOR (takenfrom fpstate->user_size).

While not really     useful, except for the initial part any of them may be of zero length, i.e. carry no data at all. Besides     a certain initial portion of the to be transferred data, these parts are directly translated into what     Linux calls SKB fragments. Such converted request parts can, when for a particular SKB they are all of     length zero, lead to a de-reference of NULL in core networking code. (CVE-2023-46838)

  - The brcm80211 component in the Linux kernel through 6.5.10 has a brcmf_cfg80211_detach use-after-free in     the device unplugging (disconnect the USB by hotplug) code. For physically proximate attackers with local     access, this could be exploited in a real world scenario. This is related to     brcmf_cfg80211_escan_timeout_worker in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c.

  - An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4     (netfilter: nf_tables: Reject tables of unsupported family); While creating a new netfilter table, lack of     a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function enables an     attacker to achieve out-of-bounds access. (CVE-2023-6040)

  - A vulnerability was found in vhost_new_msg in drivers/vhost/vhost.c in the Linux kernel, which does not     properly initialize memory in messages passed between virtual guests and the host operating system in the     vhost/vhost.c:vhost_new_msg() function. This issue can allow local privileged users to read some kernel     memory contents when reading from the /dev/vhost-net device file. (CVE-2024-0340)

  - A use-after-free flaw was found in the __ext4_remount in fs/ext4/super.c in ext4 in the Linux kernel. This     flaw allows a local user to cause an information leak problem while freeing the old quota file names     before a potential failure, leading to a use-after-free. (CVE-2024-0775)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error     within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when     NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit     f342de4e2f33e0e39165d8639387aa6c19dff660. (CVE-2024-1086)
