CVE-2020-8835

An out-of-bounds access flaw was found in the Linux kernel’s implementation of the eBPF code verifier, where an incorrect register bounds calculation while checking 32-bit instructions in an eBPF program occurs. This flaw allows an unprivileged user or process to execute eBPF programs to crash the kernel, resulting in a denial of service or potentially gaining root privileges on the system.

This issue does not affect the versions of the kernel package as shipped with Red Hat Enterprise Linux 5, 6, 7 and 8 and Red Hat Enterprise MRG 2.
