In the Linux kernel, the following vulnerability has been resolved: sctp: fix a potential overflow in sctp_ifwdtsn_skip Currently, when traversing ifwdtsn skips with _sctp_walk_ifwdtsn, it only checks the pos against the end of the chunk. However, the data left for the last pos may be < sizeof(struct sctp_ifwdtsn_skip), and dereference it as struct sctp_ifwdtsn_skip may cause coverflow. This patch fixes it by checking the pos against "the end of the chunk - sizeof(struct sctp_ifwdtsn_skip)" in sctp_ifwdtsn_skip, similar to sctp_fwdtsn_skip.

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-005773 advisory.

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

    sctp: fix a potential overflow in sctp_ifwdtsn_skip

    Currently, when traversing ifwdtsn skips with _sctp_walk_ifwdtsn, it only     checks the pos against the end of the chunk. However, the data left for     the last pos may be < sizeof(struct sctp_ifwdtsn_skip), and dereference     it as struct sctp_ifwdtsn_skip may cause coverflow.

    This patch fixes it by checking the pos against the end of the chunk -     sizeof(struct sctp_ifwdtsn_skip) in sctp_ifwdtsn_skip, similar to     sctp_fwdtsn_skip.

The version of kernel installed on the remote host is prior to 5.4.241-150.347. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2023-044 advisory.

    A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that     allows local users to create files for the XFS file-system with an unintended group ownership and with     group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a     certain group and is writable by a user who is not a member of this group. This can lead to excessive     permissions granted in case when they should not.  This vulnerability is similar to the previous     CVE-2018-13405 and adds the missed fix for the XFS. (CVE-2021-4037)

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

    tun: avoid double free in tun_free_netdev (CVE-2021-47082)

    A double-free flaw was found in the Linux kernel's TUN/TAP device driver functionality in how a user     registers the device when the register_netdevice function fails (NETDEV_REGISTER notifier). This flaw     allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-4744)

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

    gfs2: Always check inode size of inline inodes (CVE-2022-49739)

    A use-after-free flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux Kernel due to a race     problem. This flaw leads to a denial of service issue. (CVE-2023-0590)

    An out-of-bounds memory access flaw was found in the Linux kernel's XFS file system in how a user restores     an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or     potentially escalate their privileges on the system. (CVE-2023-2124)

    An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The     userspace data->block[0] variable was not capped to a number between 0-255 and was used as the size of a     memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to     crash the system or potentially achieve code execution. (CVE-2023-2194)

    do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference). (CVE-2023-28466)

    The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in     drivers/net/ethernet/qualcomm/emac/emac.c if a physically proximate attacker unplugs an emac based device.
