CVE-2026-53085

A flaw was found in the Linux kernel's Berkeley Packet Filter (BPF) subsystem. This use-after-free vulnerability occurs when the task_vma iterator reads task memory without properly acquiring a reference, allowing the memory structure to be freed concurrently while still in use. This can lead to system instability or a denial of service (DoS). Additionally, improper handling of interrupt-disabled contexts could result in a deadlock.

This CVE has been rated as Moderate because eBPF (and XDP) is restricted to root-only on Red Hat Enterprise Linux.
