CVE-2026-97950
In the Linux kernel, the following vulnerability has been resolved: configfs: pin the symlink target's dirent instead of chasing -cidentry createlink reads the target's configfsdirent from item-cidentry-dfsdata, relying on the item reference taken by gettarget. That reference pins the item, not i...
CVE-2026-97546: Undefined Security Weakness
In the Linux kernel, the following vulnerability has been resolved: xfs: don't spin forever on zero-length dirents when salvaging them LOLLM noticed that xrepdirrecoverdata can spin forever if it encounters an unused dirent that claims to have length zero. Fix that, and prevent the same thing fro...

CVE-2026-38636
The relibc library, specifically in commit 61f42d , contains a vulnerability in the seekdir() function located at /dirent/mod.rs. An attacker can exploit this issue by providing a crafted input to trigger a Denial of Service (DoS) . While the specific technical mechanism of the resource consumpti...
CVE-2026-46078
In the Linux kernel, the following vulnerability has been resolved: erofs: fix the out-of-bounds nameoff handling for trailing dirents Currently we already have boundary-checks for nameoffs, but the trailing dirents are special since the namelens are calculated with strnlen with unchecked nameoff...
CVE-2026-46078
Summary: CVE-2026-46078 affects the Linux kernel EROFS filesystem, where trailing dirents can trigger an out-of-bounds read due to incorrect nameoff handling. The root cause is that namelen calculations for trailing dirents use strnlen with unchecked nameoffs, allowing underflow when nameoff >...

CVE-2026-34962
barebox version prior to 2026.04.0 contains a denial-of-service vulnerability in ext4 directory parsing in fs/ext4/ext4common.c where the ext4fsiteratedir function fails to validate that directory entry length values are non-zero. Attackers can supply a malicious ext4 filesystem image with a...
Linux kernel fuse_add_dirent_to_cache function buffer overflow vulnerability
Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A buffer overflow vulnerability exists in the Linux kernel. The vulnerability stems from the fuseadddirenttocache function not checking if the dirent size exceeds PAGESIZE, whi...
SUSE CVE-2026-31694
In the Linux kernel, the following vulnerability has been resolved: fuse: reject oversized dirents in page cache fuseadddirenttocache computes a serialized dirent size from the server-controlled namelen field and copies the dirent into a single page-cache page. The existing logic only checks...
CVE-2026-31694
A flaw was found in the Linux kernel's Filesystem in Userspace FUSE component. A malicious FUSE server could exploit this by providing an oversized directory entry dirent that is not properly validated. This improper validation causes a memory copy operation to write beyond the allocated buffer,...
