A race condition occurred between the functions lmLogClose and txEnd in JFS, in the Linux Kernel, executed in different threads. This flaw allows a local attacker with normal user privileges to crash the system or leak internal kernel information.

The version of kernel installed on the remote host is prior to 4.14.328-174.540. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1883 advisory.

    2024-04-11: CVE-2023-42754 was added to this advisory.

    A race condition between two functions, lmLogClose() and txEnd(), in the Linux kernel's JFS filesystem can     lead to a use-after-free vulnerability and crash. (CVE-2023-3397)

    A flaw in the kernel Xen event handler can cause a deadlock with Xen console handling in unprivileged Xen     guests. (CVE-2023-34324)

    A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was     assumed to be associated with a device before calling __ip_options_compile, which is not always the case     if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash     the system. (CVE-2023-42754)

    A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf)     component can be exploited to achieve local privilege escalation.

    If perf_read_group() is called while an event's sibling_list is smaller than its child's sibling_list, it     can increment or write to memory locations outside of the allocated buffer.

    We recommend upgrading past commit 32671e3799ca2e4590773fd0e63aaa4229e50c06. (CVE-2023-5717)

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 5.10.199-190.747. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2023-043 advisory.

    2024-07-03: CVE-2023-52504 was added to this advisory.

    2024-06-06: CVE-2023-52477 was added to this advisory.

    A race condition between two functions, lmLogClose() and txEnd(), in the Linux kernel's JFS filesystem can     lead to a use-after-free vulnerability and crash. (CVE-2023-3397)

    An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access     to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES     emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege     escalation). This depends on a race condition through which userspace can replace an instruction before     the #VC handler reads it. (CVE-2023-46813)

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

    usb: hub: Guard against accesses to uninitialized BOS descriptors (CVE-2023-52477)
