kernel: fork: defer linking file vma until vma is fully initialized

A flaw was found in the Linux kernel. A race condition can occur when the fork system call is called due to improper locking, triggering a warning, impacting system stability, and resulting in a denial of service...

kernel: filelock: Remove locks reliably when fcntl/close race is detected

In the Linux kernel, the following vulnerability has been resolved: filelock: Remove locks reliably when fcntl/close race is detected When fcntlsetlk races with close, it removes the created lock with dolockfilewait. However, LSMs can allow the first dolockfilewait that created the lock while...

kernel: scsi: qedf: Make qedf_execute_tmf() non-preemptible

A vulnerability was found in the Linux kernel's qedf driver function qedfexecutetmf, where the function call smpprocessorid is done from preemptible code before acquiring a lock which can result in BUGON when running an RT kernel. This can result in system inconsistencies...

kernel: gfs2: Fix potential glock use-after-free on unmount

A vulnerability was found in the Linux kernel within the gfs2 component, where potential use-after-free issues could occur on unmount. When DLM lockspaces are released with remaining locks, callbacks for asynchronous lock contention may access freed objects, causing unexpected behavior...
