CVE-2026-45878

A flaw was found in the Linux kernel's AMD KFD Kernel Fusion Driver component. A local user could exploit a boundary error in the debug address watch v2 functionality by providing a specially crafted watchid. This could lead to a buffer overflow, potentially allowing memory access outside of...

CVE-2026-46040

A flaw was found in the Linux kernel's inotify subsystem. When the fsnotifyaddinodemarklocked function fails during the creation of a new watch, the system does not properly decrement the watch count. This oversight can lead to a watch count leak, where repeated failures exhaust the maximum user...

CVE-2026-46040

CVE-2026-46040: In the Linux kernel inotify path, when fsnotify_add_inode_mark_locked() fails during inotify_new_watch(), the error path did not call dec_inotify_watches(), leaking a watch count and potentially exhausting max_user_watches (-ENOSPC) even with no active watches. The fix introduces ...

CVE-2026-45878

The CVE-2026-45878 issue affects the Linux kernel’s AMD GPU driver (drm/amdkfd) where debug address watch (watch_id) handling could overflow memory due to mixing unsigned watch_id with signed checks. The root cause is insufficient bounds validation for watch_id, which could be large enough to acc...
