CVE-2026-89710

A flaw was found in the Linux kernel's NFSv4.1 implementation. When a server returns a new layout state identifier while an existing one is still active, the pnfslayoutprocess function fails to properly release memory associated with layout segments. This oversight leads to a memory leak, which...

CVE-2026-89631

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote malicious SMB server could send a specially crafted tree connect response with a byte count that is too small. This incorrect handling can lead to an integer underflow, causing the client to read beyond an allocated...
