Description OSIDB Bzimport 2026-03-25 11:03:57 UTC
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.
