kernel: drm: Don't unref the same fb many times by mistake due to deadlock handling

A flaw was found in the Linux kernel. A frame buffer can be freed while still in use in a specific situation in drivers/gpu/drm/drmplane.c. This issue may compromise the availability...

kernel: md/raid5: fix deadlock that raid5d() wait for itself to clear MD_SB_CHANGE_PENDING

A vulnerability was found in the Linux kernel's md/raid5 implementation within the raid5d function. This flaw can cause a deadlock when handling I/O operations due to a conflict between the reconfigmutex and the MDSBCHANGEPENDING flag, leading to excessive CPU usage and denial of service...

kernel: scsi: lpfc: Release hbalock before calling lpfc_worker_wake_up()

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Release hbalock before calling lpfcworkerwakeup lpfcworkerwakeup calls the lpfcworkdone routine, which takes the hbalock. Thus, lpfcworkerwakeup should not be called while holding the hbalock to avoid potential deadlo...
