Deadlock Vulnerability in Linux Kernel Affects Radeon Graphics Products
CVE-2025-68223
What is CVE-2025-68223?
A vulnerability in the Linux kernel affecting Radeon graphics products allows for potential deadlocks due to improper handling of the mutex and wait queue associated with the fence lock. The issue arises when an attempt is made to progress the queue while determining if a fence is signaled, which is unnecessary and can lead to self-deadlock situations. This was addressed by modifying the behavior of the dma-fence operations to prevent these conflicting operations, ensuring greater system reliability and stability.
