REDHAT-BUG-2324617: Low severity linux kernel vulnerability
In the Linux kernel, the following vulnerability has been resolved:
drm/radeon: Fix encoder->possibleclones
Include the encoder itself in its possibleclones bitmask. In the past nothing validated that drivers were populating possibleclones correctly, but that changed in commit 74d2aacbe840 ("drm: Validate encoder->possibleclones"). Looks like radeon never got the memo and is still not following the rules 100% correctly.
This results in some warnings during driver initialization: Bogus possibleclones: [ENCODER:46:TV-46] possibleclones=0x4 (full encoder mask=0x7) WARNING: CPU: 0 PID: 170 at drivers/gpu/drm/drmmodeconfig.c:615 drmmodeconfigvalidate+0x113/0x39c ...
(cherry picked from commit 3b6e7d40649c0d75572039aff9d0911864c689db)
