NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-modules package and not the kernel-modules package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

In the Linux kernel through 5.16.10, certain binary files may have the exec-all attribute if they were built in approximately 2003 (e.g., with GCC 3.2.2 and Linux kernel 2.4.20). This can cause execution of bytes located in supposedly non-executable regions of a file.
