CVE-2026-72307

A flaw was found in the Linux kernel's mlxsw driver. When the mlxswspvrslpmtreereplace function encounters an error during Virtual Router VR replacement operations, its rollback mechanism fails to correctly release resources. This leads to a reference count leak, where system resources are not...

CVE-2026-72308

A flaw was found in the mlxsw driver of the Linux kernel. This vulnerability occurs when the mlxswspportlagjoin function fails to properly release a network resource reference, leading to a reference count leak. Over time, this leak could exhaust system resources, potentially resulting in a denia...
