kernel: drbd: only clone bio if we have a backing device

A NULL pointer dereference was found in the Linux kernel Distributed Replicated Block Device driver's I/O request handling. A local user with privileges to perform I/O operations on a DRBD block device can trigger I/O requests when the DRBD device is configured in diskless mode no local backing...

kernel: scsi: qla2xxx: Fix crash during module load unload test

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix crash during module load unload test During purex packet handling the driver was incorrectly freeing a pre-allocated structure. Fix this by skipping that entry. System crashed with the following stack during a...

kernel: Drivers: hv: vmbus: Fix potential crash on module unload

In the Linux kernel, the following vulnerability has been resolved: Drivers: hv: vmbus: Fix potential crash on module unload The vmbus driver relies on the panic notifier infrastructure to perform some operations when a panic event is detected. Since vmbus can be built as module, it is required...

kernel: use after free in SUNRPC subsystem

A use-after-free flaw was found in the Linux kernel’s net/sunrpc/xprt.c function in the Remote Procedure Call SunRPC protocol. This flaw allows a local attacker to crash the system, leading to a kernel information leak issue...
