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: 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...
