    2024-02-15: CVE-2023-1652 was added to this advisory.

    A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing     sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw     to potentially crash the system causing a denial of service. (CVE-2022-4129)

    A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with     capabilities was found in the Linux kernel's OverlayFS subsystem in how a user copies a capable file from     a nosuid mount into another mount.

    A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing a font->width and     font->height greater than 32 to the fbcon_set_font, since there are no checks in place, a shift-out-of-     bounds occurs, leading to undefined behavior and possible denial of service. (CVE-2023-3161)

    A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux     Kernel. In this flaw an attacker with local user access may lead to a system crash or a leak of internal     kernel information. (CVE-2023-3567)
