Description

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix memory leak in ocfs2_stack_glue_init() ocfs2_table_header should be free in ocfs2_stack_glue_init() if ocfs2_sysfs_init() failed, otherwise kmemleak will report memleak. BUG: memory leak unreferenced object 0xffff88810eeb5800 (size 128): comm "modprobe", pid 4507, jiffies 4296182506 (age 55.888s) hex dump (first 32 bytes): c0 40 14 a0 ff ff ff ff 00 00 00 00 01 00 00 00 .@.............. 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<000000001e59e1cd>] __register_sysctl_table+0xca/0xef0 [<00000000c04f70f7>] 0xffffffffa0050037 [<000000001bd12912>] do_one_initcall+0xdb/0x480 [<0000000064f766c9>] do_init_module+0x1cf/0x680 [<000000002ba52db0>] load_module+0x6441/0x6f20 [<000000009772580d>] __do_sys_finit_module+0x12f/0x1c0 [<00000000380c1f22>] do_syscall_64+0x3f/0x90 [<000000004cf473bc>] entry_SYSCALL_64_after_hwframe+0x63/0xcd
