In the Linux kernel, the following vulnerability has been resolved: cifs: don't update i size in cifs do truncate without a cached handle If find writable file returns null, cifs file flush will return 0 without issuing set file size, and the outer 'if !rc' block will set i size to 0 before telli...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: ocfs2: Fixed data corruption caused by fallocate. When fallocate creates holes in the inode size, if the original size is located in the middle of the last cluster, then the portion of the block from the original size to the end ...

CVE-2026-89840

In the Linux kernel, the following vulnerability has been resolved: f2fs: validate MOVERANGE destination size F2FSIOCMOVERANGE checks the source range, but not the destination end before updating isize. A source hole can expose this: cloneblkaddrs skips NULLADDR entries and returns success, so th...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the f2fs file system where the F2FS IOC MOVE RANGE operation fails to validate the destination end before updating the i size the size of the inode. This occurs becaus...

Astra Linux – Vulnerability in Linux 5.10, Linux

A use-after-free vulnerability was discovered in the Linux kernel’s ext4 file system, particularly regarding the handling of the additional inode size for extended attributes. This flaw could allow a privileged local user to cause a system crash or other undefined behaviors...

Astra Linux – Vulnerability in u-boot

An integer overflow occurs in the ext4fsreadsymlink function in Das U-Boot before version 2025.01-rc1. This issue arises due to the use of the zalloc function, which adds one to a le32 variable. This occurs through a crafted ext4 file system with an inode size of 0xffffffff. As a result, the mall...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: gfs2: Always check the inode size of inline inodes. Check whether the inode size of inline inodes is within the allowed range when reading inodes from the disk gfs2dinodein. This prevents on-disk corruption. The two checks in...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ocfs2: Fixed data corruption after conversion from inline format. The commit 6dbf7bb55598 “fs: Do not invalidate page buffers in blockwritefullpage” uncovered a latent bug in the conversion from inline inode format to a normal...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ext4: Fixed the issue where idisksize could exceed isize in partially written cases. It is possible for idisksize to exceed isize, triggering a warning. genericperformwrite: - copied = iovitercopyfromuseratomiclen // copied...

CVE-2026-64323

A flaw was found in the Linux kernel's Universal Disk Format UDF filesystem. A local attacker could craft a malicious UDF image with a specially formed Virtual Allocation Table VAT header. When this image is mounted, the kernel fails to properly validate the VAT header length against the VAT inod...
