CVE-2023-53860

CVE-2023-53860: Linux kernel vulnerability in dm code where IO may be queued under RCU protection when REQ_NOWAIT is set. Affected behavior arises from dm looking up IO tables by request type and assuming REQ_NOWAIT implies safe scheduling under RCU read lock, which is incorrect. A sample preadv2...

CVE-2023-53786

The CVE-2023-53786 issue is in the Linux kernel dm flakey path, where a dmsetup command constructing a table can crash with a NULL pointer dereference when arg_name is NULL. The root cause is missing a NULL check before comparing arg_name; the fix adds a non-NULL check for arg_name before the com...
