The version of kernel installed on the remote host is prior to 5.4.269-183.369. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2024-062 advisory.

    2024-06-06: CVE-2023-52486 was added to this advisory.

    2024-05-23: CVE-2024-26625 was added to this advisory.

    2024-04-25: CVE-2024-26602 was added to this advisory.

    2024-04-10: CVE-2024-26598 was added to this advisory.

    2024-04-10: CVE-2023-52429 was added to this advisory.

    2024-04-10: CVE-2024-0340 was added to this advisory.

    2024-04-10: CVE-2023-52435 was added to this advisory.

    2024-04-10: CVE-2024-1151 was added to this advisory.

    dm_table_create in drivers/md/dm-table.c in the Linux kernel through 6.7.4 can attempt to (in     alloc_targets) allocate more than INT_MAX bytes, and crash, because of a missing check for struct     dm_ioctl.target_count. (CVE-2023-52429)

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

    net: prevent mss overflow in skb_segment()

    Once again syzbot is able to crash the kernel in skb_segment() [1]

    GSO_BY_FRAGS is a forbidden value, but unfortunately the followingcomputation in skb_segment() can reach     it quite easily :

    mss = mss * partial_segs;

    65535 = 3 * 5 * 17 * 257, so many initial values of mss can lead toa bad final result.

    Make sure to limit segmentation so that the new mss value is smallerthan GSO_BY_FRAGS.

    ---truncated--- (CVE-2023-52435)

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

    drm: Don't unref the same fb many times by mistake due to deadlock handling (CVE-2023-52486)

    A flaw was found in the ATA over Ethernet (AoE) driver in the Linux kernel. The aoecmd_cfg_pkts() function     improperly updates the refcnt on `struct net_device`, and a use-after-free can be triggered by racing     between the free on the struct and the access through the `skbtxq` global queue. This could lead to a     denial of service condition or potential code execution. (CVE-2023-6270)

    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 vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a     recursive operation of code push recursively calls into the code block. The OVS module does not validate     the stack depth, pushing too many frames and causing a stack overflow. As a result, this can lead to a     crash or other related issues. (CVE-2024-1151)

    A Speculative Race Condition (SRC) vulnerability that impacts modern CPU architectures supporting     speculative execution (related to Spectre V1) has been disclosed. An unauthenticated attacker can exploit     this vulnerability to disclose arbitrary data from the CPU using race conditions to access the speculative     executable code paths. (CVE-2024-2193)

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

    netfilter: nft_set_rbtree: skip end interval element from gc

    rbtree lazy gc on insert might collect an end interval element that hasbeen just added in this     transactions, skip end interval elements thatare not yet active. (CVE-2024-26581)

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

    KVM: arm64: vgic-its: Avoid potential UAF in LPI translation cache (CVE-2024-26598)

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

    sched/membarrier: reduce the ability to hammer on sys_membarrier

    On some systems, sys_membarrier can be very expensive, causing overallslowdowns for everything.  So put a     lock on the path in order toserialize the accesses to prevent the ability for this to be called attoo high     of a frequency and saturate the machine. (CVE-2024-26602)

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

    llc: call sock_orphan() at release time (CVE-2024-26625)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
