CVE-2025-68374: Linux

EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: md: fix rcu protection in md_wakeup_thread We attempted to use RCU to protect the pointer 'thread', but directly passed the value when calling md_wakeup_thread(). This means that the RCU pointer has been acquired before rcu_read_lock(), which renders rcu_read_lock() ineffective and could lead to a use-after-free.

Affected products

• Linux Linux: from 6.5, before 6.12.63 (fixed in 6.12.63); from 6.13, before 6.17.13 (fixed in 6.17.13); from 6.18, before 6.18.2 (fixed in 6.18.2)
