CVE-2026-31446

A flaw was found in the Linux kernel's ext4 filesystem. This vulnerability, a use-after-free, occurs due to a timing issue when the updatesuperwork function attempts to access memory that has already been released during a filesystem unmount operation. A local attacker could potentially exploit...

CVE-2026-31448

A flaw was found in the Linux kernel's ext4 filesystem. When creating a directory or node, if an extent insertion fails, the system may not properly clear residual data. This can lead to a situation where both directory and extended attribute xattr blocks simultaneously use the same memory buffer...

CVE-2026-35338

A vulnerability in the chmod utility of uutils coreutils allows users to bypass the --preserve-root safety mechanism. The implementation only validates if the target path is literally / and does not canonicalize the path. An attacker or accidental user can use path variants such as /../ or symbol...

CVE-2026-31438

A flaw was found in the Linux kernel's netfs component. When a process crashes and the kernel attempts to write a core dump to a 9P filesystem, the netfslimititer function does not properly handle ITERKVEC iterators. This oversight can lead to a kernel BUG, resulting in a system crash and a Denia...

CVE-2026-31437

A flaw was found in the Linux kernel's netfs component. When a write operation is retried, the netfsunbufferedwrite function can attempt to access a non-existent function, leading to a NULL pointer dereference. This vulnerability can be triggered by specific filesystem configurations, such as 9P,...

CVE-2026-31434

A flaw was found in the Linux kernel's btrfs filesystem. When sub-groups for space information are created, associated kobject names are allocated. However, these names are not properly released when the sub-groups are removed, leading to a memory leak. A local user could exploit this vulnerabili...

CVE-2026-35365

The CVE concerns the mv utility in uutils coreutils. The issue is that during moves across filesystem boundaries, the mv implementation does not preserve symbolic links; instead, it expands them and copies the linked targets as real files/directories at the destination. According to the provided ...

CVE-2026-35365 uutils coreutils mv Denial of Service and Data Duplication via Improper Symlink Expansion

The mv utility in uutils coreutils improperly handles directory trees containing symbolic links during moves across filesystem boundaries. Instead of preserving symlinks, the implementation expands them, copying the linked targets as real files or directories at the destination. This can lead to...

CVE-2026-35351 uutils coreutils mv Silent Ownership Loss in Cross-Device Operations

The mv utility in uutils coreutils fails to preserve file ownership during moves across different filesystem boundaries. The utility falls back to a copy-and-delete routine that creates the destination file using the caller's UID/GID rather than the source's metadata. This flaw breaks backups and...

CVE-2026-35344

The dd utility in uutils coreutils suppresses errors during file truncation operations by unconditionally calling Result::ok on truncation attempts. While intended to mimic GNU behavior for special files like /dev/null, the uutils implementation also hides failures on regular files and directorie...

CVE-2026-35344 uutils coreutils dd Silent Data Corruption via Unconditional Truncation Error Suppression

The dd utility in uutils coreutils suppresses errors during file truncation operations by unconditionally calling Result::ok on truncation attempts. While intended to mimic GNU behavior for special files like /dev/null, the uutils implementation also hides failures on regular files and directorie...

CVE-2026-35338

Summary: CVE-2026-35338 affects the chmod utility in the uutils coreutils package. The vulnerability arises because the implementation only checks if the target path is exactly “/” and does not canonicalize the path, allowing path variants like “/../” or symbolic links to bypass --preserve-root. ...

CVE-2026-35338 uutils coreutils chmod Path Traversal Bypass of --preserve-root

A vulnerability in the chmod utility of uutils coreutils allows users to bypass the --preserve-root safety mechanism. The implementation only validates if the target path is literally / and does not canonicalize the path. An attacker or accidental user can use path variants such as /../ or symbol...
