Does this matter?
Lower severity and a low EPSS score (0.28%). Track it; it rarely justifies an emergency change on its own.
Description
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.
