Description SMASH SMASH 2024-03-27 10:02:59 UTC 
Mesa v23.0.4 was discovered to contain a NULL pointer dereference via the function dri2GetGlxDrawableFromXDrawableId(). This vulnerability is triggered when the X11 server sends an DRI2_BufferSwapComplete event unexpectedly when the application is using DRI3. NOTE: this is disputed because there is no scenario in which the vulnerability was demonstrated.

Ok. Thanks. Not sure what to do with this now. I would like to at least watch the issue on gitlab fdo, but seems this is not supported. I could try to poll this from time to time. But no promises given.
