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-2026-46078
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 >...
