Linux Distros Unpatched Vulnerability : CVE-2026-89698

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - nfsd: widen nfsdgenlrqstp address fields to sockaddrstorage struct nfsdgenlrqstp declares rqdaddr and rqsaddr as plain struct sockaddr 16 bytes. When an IPv6 NF...

CVE-2026-89691

A flaw was found in the Linux kernel's Network File System Daemon nfsd component. The nfsd4releasecompoundargs function does not properly clear an internal counter opcnt when releasing a buffer. This oversight can lead to an out-of-bounds read, allowing an attacker to access adjacent memory and...

CVE-2026-80996

A flaw was found in the Linux kernel's L2TP Layer 2 Tunneling Protocol networking component. Specifically, the netlink handlers responsible for creating and modifying L2TP tunnels and sessions may fail to propagate multicast notification errors. This can lead to calling applications retrying...

CVE-2026-89700

In the Linux kernel, the following vulnerability has been resolved: nfsd: validate sockaddr length per family in listenerset nfsdsocknlpolicy declares NFSDASOCKADDR as a bare NLABINARY attribute with no minimum length. A CAPNETADMIN caller can send a 16-byte NFSDASOCKADDR with safamily=AFINET6,...

DEBIAN-CVE-2026-89690

In the Linux kernel, the following vulnerability has been resolved: nfsd: defer vfree of compound ops to fix rpcstatus UAF The rpcstatus netlink dumpit walks every in-flight svcrqst under rcureadlock and, for NFSv4 requests, reads opnums out of args-ops. But args-ops is a separate vmalloc buffer...
