NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-debuginfo-common-x86_64 package and not the kernel-rt-debuginfo-common-x86_64 package as distributed by Rocky-Linux. See How to fix? for Rocky-Linux:8 relevant fixed versions and status.

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. This uid mapping bug allows a local user to escalate their privileges on the system.
