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): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace (crc 6265fd77): [<ffffffff993495ed>] kmalloc_trace+0x29d/0x340 [<ffffffffc0ea4a94>] dm_dmub_sw_init+0xb4/0x450 [amdgpu] [<ffffffffc0ea4e55>] dm_sw_init+0x15/0x2b0 [amdgpu] [<ffffffffc0ba8557>] amdgpu_device_init+0x1417/0x24e0 [amdgpu] [<ffffffffc0bab285>] amdgpu_driver_load_kms+0x15/0x190 [amdgpu] [<ffffffffc0ba09c7>] amdgpu_pci_probe+0x187/0x4e0 [amdgpu] [<ffffffff9968fd1e>] local_pci_probe+0x3e/0x90 [<ffffffff996918a3>] pci_device_probe+0xc3/0x230 [<ffffffff99805872>] really_probe+0xe2/0x480 [<ffffffff99805c98>] __driver_probe_device+0x78/0x160 [<ffffffff99805daf>] driver_probe_device+0x1f/0x90 [<ffffffff9980601e>] __driver_attach+0xce/0x1c0 [<ffffffff99803170>] bus_for_each_dev+0x70/0xc0 [<ffffffff99804822>] bus_add_driver+0x112/0x210 [<ffffffff99807245>] driver_register+0x55/0x100 [<ffffffff990012d1>] do_one_initcall+0x41/0x300
Fix this by freeing dmub_srv after destroying it.
