The version of kernel installed on the remote host is prior to 4.14.313-235.533. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2027 advisory.

    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)

    An insufficient permission check has been found in the Bluetooth subsystem ofthe Linux kernel when     handling ioctl system calls of HCI sockets. This causestasks without the proper CAP_NET_ADMIN capability     can easily mark HCI socketsas _trusted_. Trusted sockets are intended to enable the sending and     receivingof management commands and events, such as pairing or connecting with a newdevice.  As a result,     unprivileged users can acquire a trusted socket, leadingto unauthorized execution of management commands.
    The exploit requires onlythe presence of a set of commonly used setuid programs (e.g., su, sudo).
    (CVE-2023-2002)

    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)

    cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes     indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23454)

    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)

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)

    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.
