CVE-2024-35808: Improper Locking

In the Linux kernel, the following vulnerability has been resolved: md/dm-raid: don't call mdreapsyncthread directly Currently mdreapsyncthread is called from raidmessage directly without holding 'reconfigmutex', this is definitely unsafe because mdreapsyncthread can change many fields that is...

kernel: Linux kernel: md/raid10 soft lockup due to unlimited plugged bio

A flaw was found in the Linux kernel's Multiple Device MD driver, specifically within the RAID10 implementation. This vulnerability allows a local user to trigger a soft lockup, leading to a Denial of Service DoS. The issue arises because the md/raid10 component lacks a limit on plugged bio block...

kernel: md/raid5-cache: fix a deadlock in r5l_exit_log()

A deadlock vulnerability was found in the md RAID5 cache r5l subsystem in the Linux kernel. In r5lexitlog, flushwork is called while holding reconfigmutex, which waits for disablewritebackwork to complete. However, r5cdisablewritebackasync calls waitevent which requires conf-log to be NULL, but...

kernel: md: don't dereference mddev after export_rdev()

A use-after-free vulnerability was found in the Linux kernel multiple device RAID subsystem's device lifetime management. A local user with privileges to manage MD arrays can trigger concurrent device addition and removal operations via sysfs, causing a race condition where the mddev structure is...
