CVE-2026-89567

CVE-2026-89567 affects the jbd2 (Journalling Block Device v2) subsystem of the Linux kernel . The root cause is that the jbd2 shrinker accounts only successfully released checkpoint buffers against its scan budget (nr_to_scan ), meaning busy buffers consume no budget. If a checkpoint transaction ...
