A use-after-free vulnerability in the Linux kernel's BPF subsystem was fixed. The issue occurs when querying information for offloaded BPF maps or programs, where a network namespace reference count may reach zero during destruction, causing a use-after-free condition. The fix replaces get_net() with maybe_get_net() to safely handle network namespace reference counts. This vulnerability affects multiple Linux kernel versions prior to 7.0.0-28.28 and related builds. A patch is available and should be applied to mitigate the issue. Join the discussion | GCVE Database | 06/24/2026, 17:17:00 UTC Added: 07/17/2026, 10:17:24 UTC |
