CVE-2026-89699

A flaw was found in the Linux kernel's Network File System Daemon nfsd when handling NFSv4 CREATE operations. A remote attacker can exploit this by sending a crafted request with an oversized symbolic link symlink target length. This unbounded length can force the kernel to allocate a large amoun...

CVE-2026-89699

This vulnerability affects the Linux kernel 's NFS server daemon (nfsd ), specifically the nfsd4_decode_create() function handling NFSv4 CREATE operations with NF4LNK symlink targets. The root cause is an unbounded cr_datalen accepted from the wire, allowing a client to force a kmalloc of several...
