CVE-2026-98398

The Linux kernel contains a vulnerability in the lockdep subsystem where stale class_cache entries are not invalidated when a lock class is zapped (e.g., during module unload or key unregistration). This occurs because zap_class() removes the class from the hash table but does not clear pointers ...

CVE-2026-43115

The CVE-2026-43115 entry documents a Linux kernel fix for Tiny SRCU: srcu_gp_start_if_needed() previously called schedule_work(), acquiring pool->lock and triggering a lockdep splat when call_srcu() runs with a scheduler lock held. The remediation adds irq_work_sync() to cleanup_srcu_struct() ...

CVE-2026-43115: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: srcu: Use irqwork to start GP in tiny SRCU Tiny SRCU's srcugpstartifneeded directly calls schedulework, which acquires the workqueue pool-lock. This causes a lockdep splat when callsrcu is called with a scheduler lock held, due t...
