Description SMASH SMASH 2024-06-03 17:31:26 UTC 
In the Linux kernel, the following vulnerability has been resolved:

thermal/debugfs: Free all thermal zone debug memory on zone removal

Because thermal_debug_tz_remove() does not free all memory allocated for
thermal zone diagnostics, some of that memory becomes unreachable after
freeing the thermal zone's struct thermal_debugfs object.

Address this by making thermal_debug_tz_remove() free all of the memory
in question.

Pertains only to stable including the fix.  Nothing to do.  Switching back to security team.
