RHEL 9 : kpatch-patch (RHSA-2024:1055)

high Nessus Plugin ID 191441

Synopsis

The remote Red Hat host is missing a security update for kpatch-patch.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2024:1055 advisory.

- A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This could allow a local unprivileged user to escalate their privileges on the system. (CVE-2023-6546)

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

Solution

Update the RHEL kpatch-patch package based on the guidance in RHSA-2024:1055.
