A flaw was found in the Linux kernel's networking subsystem. When page pool statistics are enabled, a race condition in the bulk recycling mechanism can allow a memory pool to be freed before statistical updates finish processing. An attacker capable of triggering concurrent network buffer teardown could exploit this use-after-free flaw to cause a Denial of Service (DoS) via a system crash or potentially corrupt system memory.
