CVE-2026-74479

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A use-after-free issue exists in the pktgen component of the Linux kernel. The problem occurs when pktgen change name() replaces pkt dev->entry while holding the t->if lock lock, while pktgen remove device() attempts to remove the same entry before the rem dev from if list() function acquires that lock. This race condition allows a kthread to pass a stale proc dir entry to the proc remove() function after the rename path has already freed it, leading to a slab-use-after-free.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
