Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.4.0-rc7+ #154
Description
The Linux kernel contains a flaw within the virtio pmem subsystem. Specifically, the
submit bio noacct() function requires the bio operation to be either WRITE or ZONE APPEND for flush bios, but async pmem flush() does not assign the REQ OP WRITE flag when allocating flush bios. This results in failures during flush operations. The issue occurs when performing mkfs.xfs on a pmem device. The fix involves adding the missing REQ OP WRITE flag for flush bios.Recommendations
Update to Linux kernel version 6.4.0-rc7+ #154 or later.
