CWE-20

Description

An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAP_BPF privileges to escalate privileges and execute arbitrary code in the context of the kernel.

Affected configurations

• linux linux kernel (>= 5.19 < 6.3) • fedoraproject fedora 38 • redhat enterprise linux 9.0
