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...

CVE-2026-46023

CVE-2026-46023 is a Linux kernel vulnerability in dm-mirror where create_dirty_log() could bypass argc checks due to an unsigned add of 2 + param_count, allowing an out-of-bounds read in argv when param_count is near UINT_MAX. The root cause is an overflow in argument count calculation before val...
