Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: f2fs: fixed the issue of not checking the atomicwrite status in f2fs ioctl interfaces. Some f2fs ioctl interfaces, such as f2fsiocsetpinfile, f2fsmovefilerange, and f2fsdefragmentrange, failed to check the atomicwrite status, whi...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: f2fs: Flush the inode if the atomic file is aborted. We need to flush the inode that was aborted during the atomic operation, to avoid stale dirty inodes during eviction in this call stack: f2fsmarkinodedirtysync+0x22/0x40 f2f...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: f2fs: The issue with null-ptr-deref in f2fsgetdnodeofdata has been fixed. There are the following issues when testing the f2fs atomic write: - F2FS-fs loop0: Unable to find a valid F2FS filesystem in the 2nd superblock. - F2FS-fs...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: f2fs: fixed the inconsistency issue with the ISCHECKPOINTED flag caused by concurrent atomic commits and checkpoint writes. During SPO tests, when mounting F2FS, an -EINVAL error was returned from f2fsrecoverinodepage. This...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: f2fs: FMODEWRITE is required for atomic write IOctls. The F2FS IOctls for starting and committing atomic writes check for inodeownerorcapable, but this does not provide LSMs like SELinux or Landlock with an opportunity to deny...

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...

CVE-2026-63811: Undefined Security Weakness
