Out-of-Bounds Access in Linux Rocket DRM Due to Improper Unwinding

Publication date: 2026-03-25

Last updated on: 2026-03-25

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: accel/rocket: fix unwinding in error path in rocket_probe When rocket_core_init() fails (as could be the case with EPROBE_DEFER), we need to properly unwind by decrementing the counter we just incremented and if this is the first core we failed to probe, remove the rocket DRM device with rocket_device_fini() as well. This matches the logic in rocket_remove(). Failing to properly unwind results in out-of-bounds accesses.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability exists in the Linux kernel's rocket driver, specifically in the error handling path of the rocket_probe function.

When the rocket_core_init() function fails, such as when it returns EPROBE_DEFER, the code does not properly unwind the changes it made. This means it fails to decrement a counter it previously incremented and, if this is the first core that failed to probe, it does not remove the rocket DRM device using rocket_device_fini().

This improper unwinding leads to out-of-bounds memory accesses, which can cause instability or crashes.


How can this vulnerability impact me? :

The vulnerability can cause out-of-bounds memory accesses in the Linux kernel when the rocket driver fails to initialize properly.

Such out-of-bounds accesses may lead to system instability, crashes, or potentially allow an attacker to exploit the kernel for further malicious actions.
