VUL-0: CVE-2024-27034: kernel: f2fs: compress: fix to cover normal cluster write with cp_rwsem
Last modified: 2024-05-02 11:05:58 UTC
In the Linux kernel, the following vulnerability has been resolved: f2fs: compress: fix to cover normal cluster write with cp_rwsem When we overwrite compressed cluster w/ normal cluster, we should not unlock cp_rwsem during f2fs_write_raw_pages(), otherwise data will be corrupted if partial blocks were persisted before CP & SPOR, due to cluster metadata wasn't updated atomically.

We don't enable f2fs on any branch, so we are not affected. Closing.
