CVE-2022-50057: Linux kernel NTFS driver can crash on bad mount options
CVE-2022-50057 · published 1 year ago
Summary
The NTFS file system driver in the Linux kernel could crash if it receives an unexpected mount parameter, because it tried to use a missing pointer. This may cause a system freeze or reboot on affected kernel versions. Updating the kernel to the latest release fixes the check and prevents the crash.

fs/ntfs3: Fix NULL deref in ntfs_update_mftmirr
In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix NULL deref in ntfs_update_mftmirr If ntfs_fill_super() wasn't called then sbi->sb will be equal to NULL. Code should check this ptr before dereferencing. Syzbot hit this issue via passing wrong mount param as can be seen from log below Fail log: ntfs3: Unknown parameter 'iochvrset' general protection fault, probably for non-canonical address 0xdffffc0000000003: 0000 [#1] PREEMPT SMP KASAN KASAN: null-ptr-deref in range [0x0000000000000018-0x000000000000001f] CPU: 1 PID: 3589 Comm: syz-executor210 Not tainted 5.18.0-rc3-syzkaller-00016-gb253435746d9 #0 ...
