Description
In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix memory leak on ntfs_fill_super() error path syzbot reported kmemleak as below: BUG: memory leak unreferenced object 0xffff8880122f1540 (size 32): comm "a.out", pid 6664, jiffies 4294939771 (age 25.500s) 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 ed ff ed ff 00 00 00 00 ................ backtrace: [<ffffffff81b16052>] ntfs_init_fs_context+0x22/0x1c0 [<ffffffff8164aaa7>] alloc_fs_context+0x217/0x430 [<ffffffff81626dd4>] path_mount+0x704/0x1080 [<ffffffff81627e7c>] __x64_sys_mount+0x18c/0x1d0 [<ffffffff84593e14>] do_syscall_64+0x34/0xb0 [<ffffffff84600087>] entry_SYSCALL_64_after_hwframe+0x63/0xcd This patch fixes this issue by freeing mount options on error path of ntfs_fill_super().
A memory leak vulnerability has been identified in the Linux kernel's NTFS3 file system implementation. This issue arises in the 'ntfs_fill_super()' function, where mount options are not properly released during error handling. The vulnerability has been observed in the Linux kernel stable tree.
The vulnerability has been addressed in the Linux kernel. Users can upgrade to the latest version of the stable Linux kernel to apply the fix.
