A use-after-free vulnerability in the Linux kernel's network shaper subsystem was resolved by reworking the VALID marking mechanism. The issue involved a race condition where a reader could observe a VALID mark, get interrupted, and then fetch a different entry pointer than expected, potentially leading to use-after-free. This flaw could result in privilege escalation or system compromise. The vulnerability affects multiple versions of the linux-hwe-edge kernel prior to certain fixed versions. A patch is available and should be applied to mitigate the risk. Join the discussion | GCVE Database | 07/20/2026, 00:00:00 UTC Added: 07/21/2026, 20:00:02 UTC |
