CVE-2026-53083

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix RCU stall in bpffdarraymapclear Add a missing condresched in bpffdarraymapclear loop. For PROGARRAY maps with many entries this loop calls progarraymappokerun per entry which can be expensive, and without yielding this c...

CVE-2026-53083

The CVE-2026-53083 entry concerns the Linux kernel bpf subsystem. A missing cond_resched() in bpf_fd_array_map_clear() can cause RCU stalls when PROG_ARRAY maps have many entries, because prog_array_map_poke_run() is invoked per entry without yielding under load. The issue is triggered in the loo...
