CVE-2023-53838

Summary of CVE-2023-53838 (Linux kernel, f2fs): A race condition in the F2FS atomic write abort handling can cause inconsistent COW inode state. The mitigation fixes synchronization by using the inode lock and ensuring the Copy-On-Write (COW) inode is reusable for the entire lifetime of the atomi...

CVE-2023-53829 f2fs: flush inode if atomic file is aborted

In the Linux kernel, the following vulnerability has been resolved: f2fs: flush inode if atomic file is aborted Let's flush the inode being aborted atomic operation to avoid stale dirty inode during eviction in this call stack: f2fsmarkinodedirtysync+0x22/0x40 f2fs f2fsabortatomicwrite+0xc4/0xf0...

CVE-2023-53829

CVE-2023-53829 (Linux kernel, F2FS) is a concrete vulnerability in the F2FS file system related to flushing the inode when an atomic write is aborted. The issue arises in f2fs_evict_inode where a dirty-inode check (FI_DIRTY_INODE) triggers a kernel bug during inode eviction, as shown in the provi...
