    2024-05-23: CVE-2024-26815 was added to this advisory.

    2024-05-23: CVE-2024-26898 was added to this advisory.

    Integer Overflow or Wraparound vulnerability in Linux kernel on x86 and ARM (md, raid, raid5 modules)
    allows Forced Integer Overflow. (CVE-2024-23307)

    A malicious hypervisor can potentially break confidentiality and integrity of Linux SEV-SNP guests by
    injecting interrupts. (CVE-2024-25742)

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

    net: tls: handle backlogging of crypto requests

    Since we're setting the CRYPTO_TFM_REQ_MAY_BACKLOG flag on ourrequests to the crypto API,
    crypto_aead_{encrypt,decrypt} can return-EBUSY instead of -EINPROGRESS in valid situations. For example,
    whenthe cryptd queue for AESNI is full (easy to trigger with anartificially low
    cryptd.cryptd_max_cpu_qlen), requests will be enqueuedto the backlog but still processed. In that case,
    the async callbackwill also be called twice: first with err == -EINPROGRESS, which itseems we can just
    ignore, then with err == 0.

    Compared to Sabrina's original patch this version uses the newtls_*crypt_async_wait() helpers and converts
    the EBUSY toEINPROGRESS to avoid having to modify all the error handlingpaths. The handling is identical.
    (CVE-2024-26584)

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

    tls: fix race between tx work scheduling and socket close

    Similarly to previous commit, the submitting thread (recvmsg/sendmsg)may exit as soon as the async crypto
    handler calls complete().Reorder scheduling the work before calling complete().This seems more logical in
    the first place, as it'sthe inverse order of what the submitting thread will do. (CVE-2024-26585)

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

    net/sched: taprio: proper TCA_TAPRIO_TC_ENTRY_INDEX check (CVE-2024-26815)

    In the Linux kernel, the following vulnerability has been resolved: rds: tcp: Fix use-after-free of net in
    reqsk_timer_handler(). syzkaller reported a warning of netns tracker [0] followed by KASAN splat [1] and
    another ref tracker warning [1]. syzkaller could not find a repro, but in the log, the only suspicious
    sequence was as follows: 18:26:22 executing program 1: r0 = socket$inet6_mptcp(0xa, 0x1, 0x106) ...
    connect$inet6(r0, &(0x7f0000000080)={0xa, 0x4001, 0x0, @loopback}, 0x1c) (async) The notable thing here is
    0x4001 in connect(), which is RDS_TCP_PORT. (CVE-2024-26865)

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

    bpf: Fix stackmap overflow check on 32-bit arches (CVE-2024-26883)

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

    aoe: fix the potential use-after-free problem in aoecmd_cfg_pkts (CVE-2024-26898)

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

    x86/fpu: Keep xfd_state in sync with MSR_IA32_XFD (CVE-2024-35801)

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

    PCI/PM: Drain runtime-idle callbacks before driver removal (CVE-2024-35809)

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
