It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-299 advisory.

    2024-07-03: CVE-2023-51043 was added to this advisory.

    2024-02-01: CVE-2024-0639 was added to this advisory.

    2024-01-03: CVE-2023-39197 was added to this advisory.

    2023-10-12: CVE-2023-44466 was added to this advisory.

    2023-10-10: CVE-2022-48502 was added to this advisory.

    An issue was discovered in the Linux kernel before 6.2. The ntfs3 subsystem does not properly check for     correctness during disk reads, leading to an out-of-bounds read in ntfs_set_ea in fs/ntfs3/xattr.c.
    (CVE-2022-48502)

    An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited     to achieve local privilege escalation.

    The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-of-bounds write because lmax is updated     according to packet sizes without bounds checks.

    We recommend upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64. (CVE-2023-3611)

    A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to     achieve local privilege escalation.

    If tcf_change_indev() fails, fw_set_parms() will immediately return an error after incrementing or     decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter     and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability.

    We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f. (CVE-2023-3776)

    An out-of-bounds read vulnerability was found in Netfilter Connection Tracking (conntrack) in the Linux     kernel. This flaw allows a remote user to disclose sensitive information via the DCCP protocol.
    (CVE-2023-39197)

    An issue was discovered in net/ceph/messenger_v2.c in the Linux kernel before 6.4.5. There is an integer     signedness error, leading to a buffer overflow and remote code execution via HELLO or one of the AUTH     frames. This occurs because of an untrusted length taken from a TCP packet in ceph_decode_32.
    (CVE-2023-44466)

    In the Linux kernel before 6.4.5, drivers/gpu/drm/drm_atomic.c has a use-after-free during a race     condition between a nonblocking atomic commit and a driver unload. (CVE-2023-51043)

    A denial of service vulnerability due to a deadlock was found in sctp_auto_asconf_init in     net/sctp/socket.c in the Linux kernel's SCTP subsystem. This flaw allows guests with local user privileges     to trigger a deadlock and potentially crash the system. (CVE-2024-0639)

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.

The version of kernel installed on the remote host is prior to 5.15.122-77.145. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2023-025 advisory.

    An issue was discovered in the Linux kernel before 6.2. The ntfs3 subsystem does not properly check for     correctness during disk reads, leading to an out-of-bounds read in ntfs_set_ea in fs/ntfs3/xattr.c.
    (CVE-2022-48502)

    A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address     prediction. This may result in speculative execution at an attacker-controlled?address, potentially     leading to information disclosure. (CVE-2023-20569)

    An issue in Zen 2 CPUs, under specific microarchitectural circumstances, may allow an attacker to     potentially access sensitive information. (CVE-2023-20593)

    An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited     to achieve local privilege escalation.

    The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-of-bounds write because lmax is updated     according to packet sizes without bounds checks.
