CVE-2026-68408

The CVE affects the Linux kernel cfg80211/pmsr handling in wifi: the deadlock occurred when a PMSR session was closed during device teardown: wdev_down held wiphy_lock, while pmsr_free_wk waited to acquire the same lock via cancel_work_sync. The fix converts pmsr_free_wk from a plain work_struct ...

CVE-2026-68364

The CVE-2026-68364 entry concerns the Linux kernel DRM/AMD display subsystem. It describes a deadlock in the ISM path (dc_lock) during suspend caused by amdgpu_dm_ism_disable() waiting for ISM work that itself acquires dc_lock, creating an ABBA deadlock when a worker is in flight at suspend. The ...

CVE-2026-68319

The CVE-2026-68319 entry concerns Linux kernel code where a deadlock could occur between the PCI reset thread and removal path. The root cause was that pci_reset_function() acquires device_lock, and pdsc_remove() is invoked with that lock held; if the reset thread is active, destroy_workqueue() b...
