- Summary
- drm/radeon: Remove calls to drm_put_dev()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drm/radeon: Remove calls to drmputdev()
Since the allocation of the drivers main structure was changed to devmdrmdevalloc() drmput_dev()'ing to trigger it to be free'd should be done by devres.
However, drmputdev() is still in the probe error and device remove paths. When the driver fails to probe warnings like the following are shown because devres is trying to drmputdev() after the driver already did it.
[ 5.642230] radeon 0000:01:05.0: probe with driver radeon failed with error -22 [ 5.649605] ------------[ cut here ]------------ [ 5.649607] refcountt: underflow; use-after-free. [ 5.649620] WARNING: CPU: 0 PID: 357 at lib/refcount.c:28 refcountwarn_saturate+0xbe/0x110
