CVE-2026-46095 md/md-llbitmap: raise barrier before state machine transition

In the Linux kernel, the following vulnerability has been resolved: md/md-llbitmap: raise barrier before state machine transition Move the barrier raise operation before calling llbitmapstatemachine in both llbitmapstartwrite and llbitmapstartdiscard. This ensures the barrier is in place before a...

CVE-2026-46095

CVE-2026-46095 is a Linux kernel vulnerability resolved by moving the barrier raise before the llbitmap state machine transitions. The fix updates two functions, llbitmap_start_write() and llbitmap_start_discard(), to ensure the barrier is raised prior to any state changes, preventing a race wher...

CVE-2026-43191

A flaw was found in the Linux kernel's AMD display drm/amd/display component. An issue occurs when the physical layer's finite state machine PHY FSM incorrectly transitions during the disabling of Transition Minimized Differential Signaling TMDS output on DCN35 hardware. This can cause the Output...
