kernel: dm: fix a race condition in retrieve_deps

A use-after-free flaw was found in the Linux kernel's device-mapper multipath implementation. A race condition exists between retrievedeps and multipathmessage when devices are added or removed. The retrievedeps function walks the device list without holding a lock while multipathmessage can modi...

The vulnerabilities of the functions dm_mq_init_request_queue() and dm_mq_cleanup_mapped_device() in the Linux kernel’s drivers/md/dm-rq.c file allow attackers to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerabilities of the functions dmmqinitrequestqueue and dmmqcleanupmappeddevice in the Linux kernel’s drivers/md/dm-rq.c file are related to the repeated release of previously released memory. Exploiting these vulnerabilities could allow an attacker to compromise the confidentiality,...

kernel: dm: don't attempt to queue IO under RCU protection

A sleep-in-atomic-context bug was found in the Device Mapper subsystem in the Linux kernel. When processing REQNOWAIT requests, dm incorrectly submits I/O while holding an RCU read lock, assuming that REQNOWAIT means no scheduling can occur. However, mempoolalloc and other allocation functions ma...
