CVE-2026-46294

CVE-2026-46294 affects the Linux kernel device-mapper (dm-ioctl) in the retrieve_status path. A buffer-overflow could occur after aligning a pointer to an 8-byte boundary if the remaining length calculation wraps past the output buffer, potentially allowing writes beyond the buffer. The advisory ...

CVE-2026-46107

A flaw was found in the Linux kernel's Device Mapper dm-thin component. This vulnerability, a metadata reference count underflow, occurs in the rebalancechildren function. When an internal btree node with a single entry is shared, the system incorrectly tracks the usage of child nodes. This can...

CVE-2026-46130

A flaw was found in the Linux kernel's device-mapper verity forward error correction dm-verity-fec component. This vulnerability occurs because a function responsible for decoding parity data makes an incorrect assumption about how these data blocks are read. Under specific, non-default...
