CVE-2024-27034

A flaw was found in the Linux kernel's f2fs compression component. When overwriting a compressed cluster with a normal cluster, the cp_rwsem (read-write semaphore) was not properly locked during f2fs_write_raw_pages(). This concurrency issue could allow a local attacker to corrupt data if partial blocks were persisted before checkpoint (CP) and Superblock Operations (SPOR), as cluster metadata was not updated atomically. This can lead to data corruption.
