CVE-2026-55392

NILFS utilities through 2.3.0, fixed in commit 26efb5d, nilfssbisvalid function fails to validate slogblocksize field in NILFS2 superblock before bit-shift operations. Attackers supplying crafted NILFS2 images trigger undefined behavior through oversized shifts or out-of-memory conditions, crashi...

CVE-2026-55392

CVE-2026-55392 affects NILFS utilities up to version 2.3.0. The root cause is nilfs_sb_is_valid() not validating s_log_block_size in the NILFS2 superblock before bit-shift operations, enabling undefined behavior from oversized shifts and potential out-of-memory conditions that can crash tools lik...

Use of Uninitialized Resource

Overview Affected versions of this package are vulnerable to Use of Uninitialized Resource in the SquashFS archive handler due to uninitialized memory in the blockToNode array. An attacker can cause denial of service or potentially disclose heap information by providing a crafted SquashFS image...

A use-after-free flaw was identified due to a race between the superblock operations in the gadgetfs Linux driver. This flaw could be triggered by removing a device that is running the gadgetfs side...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: hfs: Replace BUGON with error handling for CNID count checks. In the fields nextid, foldercount, and filecount in the super block, the values were expanded to 64 bits, and mechanisms like BUGON were added to detect overflow...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: hfsplus: Ensure that sb-sfsinfo is always cleaned up. When hfsplus was converted to the new mount API, a bug was introduced by changing the allocation pattern of sb-sfsinfo. If setupbdevsuper fails after a new superblock has been...

CVE-2026-42444

NanaZip is an open source file archive. From 5.0.1252.0 to before 6.0.1698.0, a denial-of-service vulnerability exists in the littlefs filesystem image parser in NanaZip. The handler's Open method reads BlockCount directly from the attacker-controlled superblock without any validation against the...

NanaZip 数字错误漏洞

NanaZip is a compression software open source by the M2-Team. Versions of NanaZip from 5.0.1252.0 to 6.0.1698.0 contained a numerical error vulnerability. This vulnerability stemmed from the UFS/UFS2 file system image parser not verifying the value of the fsipg field in the superblock. When this...

CVE-2026-43365

A flaw was found in the Linux kernel's XFS filesystem. This vulnerability arises when the filesystem superblock, which contains critical metadata, does not correctly specify a log stripe unit. This can lead to undersized log roundoff values, causing log corruption. A local attacker could...
