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.

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.

  - 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 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)

  - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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)

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)

The version of kernel installed on the remote host is prior to 5.15.43-20.103. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2023-023 advisory.

  - An issue was discovered in fs/io_uring.c in the Linux kernel through 5.11.8. It allows attackers to cause     a denial of service (deadlock) because exit may be waiting to park a SQPOLL thread, but concurrently that     SQPOLL thread is waiting for a signal to start, aka CID-3ebba796fa25. (CVE-2021-28951)

  - A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a     privileged local account can leak kernel stack information when issuing commands to the     /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it     can be further used to defeat existing kernel protection mechanisms. (CVE-2021-3923)

  - A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading to a possible out-of-bounds     memory write in the Linux kernel's BPF subsystem due to the way a user loads BTF. This flaw allows a local     user to crash or escalate their privileges on the system. (CVE-2022-0500)

  - A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem.
    This flaw allows a local user to cause an out-of-bounds write issue. (CVE-2022-1015)

  - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a     use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel     information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)

  - A flaw was found in KVM. When updating a guest's page table entry, vm_pgoff was improperly used as the     offset to get the page's pfn. As vaddr and vm_pgoff are controllable by user-mode processes, this flaw     allows unprivileged local users on the host to write outside the userspace region and potentially corrupt     the kernel, resulting in a denial of service condition. (CVE-2022-1158)

  - A NULL pointer dereference issue was found in KVM when releasing a vCPU with dirty ring support enabled.
    This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a     kernel oops condition that results in a denial of service. (CVE-2022-1263)

  - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This     flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a     leak of internal kernel information. (CVE-2022-1353)

  - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged     user to gain root privileges. The bug allows to build several exploit primitives such as kernel address     information leak, arbitrary execution, etc. (CVE-2022-1729)

  - kernel/bpf/verifier.c in the Linux kernel through 5.15.14 allows local users to gain privileges because of     the availability of pointer arithmetic via certain *_OR_NULL pointer types. (CVE-2022-23222)

  - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of     actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()     function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This     flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)

  - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets     are in the intended state. (CVE-2022-28893)

  - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to     cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14     and later versions. (CVE-2022-29581)

  - In the Linux kernel before 5.17.3, fs/io_uring.c has a use-after-free due to a race condition in io_uring     timeouts. This can be triggered by a local user who has no access to any user namespace; however, the race     condition perhaps can only be exploited infrequently. (CVE-2022-29582)

  - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers     to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)

  - 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 flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the     Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from     suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of     the CPU similar to the speculative execution behavior kind of attacks. (CVE-2023-1637)

  - A use-after-free flaw was found in vhost_net_set_backend in drivers/vhost/net.c in virtio network     subcomponent in the Linux kernel due to a double fget. This flaw could allow a local attacker to crash the     system, and could even lead to a kernel information leak problem. (CVE-2023-1838)

  - Improper restriction of operations within the bounds of a memory buffer in some Intel(R) i915 Graphics     drivers for linux before kernel version 6.2.10 may allow an authenticated user to potentially enable     escalation of privilege via local access. (CVE-2023-28410)

  - A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in     VMware's vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash     the system due to a double-free while cleaning up vmxnet3_rq_cleanup_all, which could also lead to a     kernel information leak problem. (CVE-2023-4387)

  - A NULL pointer dereference flaw was found in vmxnet3_rq_cleanup in drivers/net/vmxnet3/vmxnet3_drv.c in     the networking sub-component in vmxnet3 in the Linux Kernel. This issue may allow a local attacker with     normal user privilege to cause a denial of service due to a missing sanity check during cleanup.
