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.

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)
