Summary
In the Linux kernel, the following vulnerability has been resolved: test_firmware: fix memory leak in test_firmware_init() When misc_register() failed in test_firmware_init(), the memory pointed by test_fw_config->name is not released. The memory leak information is as follows: unreferenced object 0xffff88810a34cb00 (size 32): comm "insmod", pid 7952, jiffies 4294948236 (age 49.060s) hex dump (first 32 bytes): 74 65 73 74 2d 66 69 72 6d 77 61 72 65 2e 62 69 test-firmware.bi 6e 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 n............... backtrace: [<ffffffff81b21fcb>] __kmalloc_node_track_caller+0x4b/0xc0 [<ffffffff81affb96>] kstrndup+0x46/0xc0 [<ffffffffa0403a49>] __test_firmware_config_init+0x29/0x380 [test_firmware] [<ffffffffa040f068>] 0xffffffffa040f068 [<ffffffff81002c41>] do_one_initcall+0x141/0x780 [<ffffffff816a72c3>] do_init_module+0x1c3/0x630 [<ffffffff816adb9e>] load_module+0x623e/0x76a0 [<ffffffff816af471>] __do_sys_finit_module+0x181/0x240 [<ffffffff89978f99>] do_syscall_64+0x39/0xb0 [<ffffffff89a0008b>] entry_SYSCALL_64_after_hwframe+0x63/0xcd
