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.
    (CVE-2023-33203)

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

    nilfs2: fix kernel-infoleak in nilfs_ioctl_wrap_copy() (CVE-2023-53035)

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

    scsi: qla2xxx: Perform lockless command completion in abort path (CVE-2023-53041)

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

    dm stats: check for and propagate alloc_percpu failure (CVE-2023-53044)

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

    dm crypt: add cond_resched() to dmcrypt_write() (CVE-2023-53051)

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

    erspan: do not use skb_mac_header() in ndo_start_xmit() (CVE-2023-53053)

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

    igb: revert rtnl_lock() that causes deadlock (CVE-2023-53060)

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

    net: usb: smsc95xx: Limit packet length to skb->len (CVE-2023-53062)

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

    qed/qed_sriov: guard against NULL derefs from qed_iov_get_vf_info (CVE-2023-53066)

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

    scsi: scsi_dh_alua: Fix memleak for 'qdata' in alua_activate() (CVE-2023-53078)

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

    ocfs2: fix data corruption after failed write (CVE-2023-53081)

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

    cifs: fix DFS traversal oops without CONFIG_CIFS_DFS_UPCALL (CVE-2023-53246)

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

    sctp: check send stream number after wait_for_sndbuf (CVE-2023-53296)

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

    can: bcm: bcm_tx_setup(): fix KMSAN uninit-value in vfs_write (CVE-2023-53344)

    sctp: fix a potential overflow in sctp_ifwdtsn_skip (CVE-2023-53372)

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

    tracing: Free error logs of tracing instances (CVE-2023-53375)

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

    nilfs2: fix sysfs interface lifetime (CVE-2023-53440)

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

    nilfs2: fix potential UAF of struct nilfs_sc_info in nilfs_segctor_thread() (CVE-2023-53608)

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

    mm/swap: fix swap_info_struct race between swapoff and get_swap_pages() (CVE-2023-53623)
