Description
In the Linux kernel, the following vulnerability has been resolved: drm/imagination: fix firmware memory leaks Free the memory used to hold the results of firmware image processing when the module is unloaded. Fix the related issue of the same memory being leaked if processing of the firmware image fails during module load. Ensure all firmware GEM objects are destroyed if firmware image processing fails. Fixes memory leaks on powervr module unload detected by Kmemleak: unreferenced object 0xffff000042e20000 (size 94208): comm "modprobe", pid 470, jiffies 4295277154 hex dump (first 32 bytes): 02 ae 7f ed bf 45 84 00 3c 5b 1f ed 9f 45 45 05 .....E..<[...EE. d5 4f 5d 14 6c 00 3d 23 30 d0 3a 4a 66 0e 48 c8 .O].l.=#0.:Jf.H. backtrace (crc dd329dec): kmemleak_alloc+0x30/0x40 ___kmalloc_large_node+0x140/0x188 __kmalloc_large_node_noprof+0x2c/0x13c __kmalloc_noprof+0x48/0x4c0 pvr_fw_init+0xaa4/0x1f50 [powervr] unreferenced object 0xffff000042d20000 (size 20480): comm "modprobe", pid 470, jiffies 4295277154 hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 09 00 00 00 0b 00 00 00 ................ 00 00 00 00 00 00 00 00 07 00 00 00 08 00 00 00 ................ backtrace (crc 395b02e3): kmemleak_alloc+0x30/0x40 ___kmalloc_large_node+0x140/0x188 __kmalloc_large_node_noprof+0x2c/0x13c __kmalloc_noprof+0x48/0x4c0 pvr_fw_init+0xb0c/0x1f50 [powervr]
