CVE-2026-42616

A flaw was found in NTFS-3G. An attacker can trigger a heap buffer overflow in the ntfscat utility by providing a specially crafted NTFS filesystem image. When the utility attempts to read a file from the malicious image, heap memory is corrupted, which can lead to a Denial of Service DoS crash o...

CVE-2026-88832

The BusyBox utility is vulnerable to a heap buffer overflow during romfs volume ID parsing . The root cause is the use of an unbounded strlen on attacker-controlled metadata, which leads to an unbounded memcpy into a fixed-size label buffer when processing crafted filesystem images. Practical con...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: fs: hfsplus: removing WARNON from hfspluscatread,writeinode. The syzbot tool encounters WARNON in hfspluscatread,writeinode, where a crafted filesystem image may contain invalid lengths. These conditions do not constitute kernel...

CVE-2026-71220 Gfs2-utils: gfs2-utils: stack out-of-bounds write via unchecked di_height in gfs2_edit

A stack out-of-bounds write vulnerability was found in gfs2-utils. In gfs2edit, the diheight field from on-disk inode metadata is used as an array index without bounds checking, causing a stack buffer overflow that may lead to arbitrary code execution when processing crafted GFS2 filesystem image...

CVE-2026-13215 Zephyr ext2 mount: unvalidated superblock block size causes out-of-bounds write from a crafted filesystem image

The Zephyr ext2 filesystem driver fails to validate the slogblocksize field of the on-disk superblock when mounting a filesystem. ext2verifydisksuperblock in subsys/fs/ext2/ext2impl.c checks the magic number, revision, inode size and group counts, but never bounds slogblocksize. On a successful...
