CVE-2022-49742

MediumCVSS 5.5/10Last modified Aug 15, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

f2fs: initialize locks earlier in f2fs_fill_super()

syzbot is reporting lockdep warning at f2fs_handle_error() [1], for spin_lock(&sbi->error_lock) is called before spin_lock_init() is called. For safe locking in error handling, move initialization of locks (and obvious structures) in f2fs_fill_super() to immediately after memory allocation.
