Detail

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Fix memory leak in dm_sw_fini()

After destroying dmub_srv, the memory associated with it is not freed, causing a memory leak:

unreferenced object 0xffff896302b45800 (size 1024):
comm "(udev-worker)", pid 222, jiffies 4294894636
hex dump (first 32 bytes):
