CVE-2026-63811

Summary of CVE-2026-63811 (Linux kernel, f2fs) : A defect in atomic writes for F2FS can cause a mismatch between the cryptographic context used for decrypted reads and the actual on-disk data, due to how the COW inode and original inode are chosen for page reads. The read path may decrypt data us...
