CVE-2022-49376

CVE-2022-49376 affects the Linux kernel SCSI subsystem (sd driver). The issue arises when sd_probe() hits an early error before sdkp->device is initialized, leading to a NULL pointer dereference inside sd_is_zoned() due to an unintended call to sd_zbc_release_disk(). The fix removes the sd_zbc...

CVE-2022-49338 net/mlx5e: CT: Fix cleanup of CT before cleanup of TC ct rules

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: CT: Fix cleanup of CT before cleanup of TC ct rules CT cleanup assumes that all tc rules were deleted first, and so is free to delete the CT shared resources e.g the draction fwdaction which is shared for all tuples. B...
