CVE-2026-46130

CVE-2026-46130 concerns the Linux kernel’s dm-verity-fec component. The root cause is an incorrect assumption about parity data layout: when reading parity bytes across blocks, parity bytes for the first RS codeword can be split across parity blocks, causing an out-of-bounds read under certain no...

CVE-2026-46107

In Linux kernel dm-thin, a metadata refcount underflow in rebalance_children has been resolved. If an internal btree node with a single entry is shared (refcount > 1), downgrading the child without updating grandchildren leads to mismatched reference counts and can produce device mapper: space...
