DESCRIPTION
* CVE-2023-0386: Privilege escalation in Overlay filesystem.
A uid mapping bug in OverlayFS when copying a capable file from a nosuid
mount into another mount may allow a low-privileged user to run a binary
as root. A local unprivileged user can use this flaw to gain
administrative privileges on the system.
* CVE-2023-1829: Use-after-free in traffic control index filter.
A flaw in tcindex when deactivating filters can lead to a double-free. A
local attacker could use this flaw to cause a denial-of-service or
elevate privileges on the system.
