Linux Distros Unpatched Vulnerability : CVE-2026-89673

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - nfsd: fix XDR padding calculation in ffencodegetdeviceinfo nfsd4ffencodegetdeviceinfo computes the daaddrbody reservation as 16 + netidlen + addrlen, but the...

CVE-2026-89673

A flaw was found in the Linux kernel's NFS daemon nfsd. A remote attacker could exploit an error in the XDR External Data Representation padding calculation within the ffencodegetdeviceinfo function. This mismatch between reserved and actual data size leads to the leakage of stale reply-page...

CVE-2026-89673

A Linux kernel bug in the nfsd flexfiles implementation causes a XDR padding miscalculation in nfsd4_ff_encode_getdeviceinfo(). The function reserves space as 16 + netid_len + addr_len, but the subsequent xdr_encode_opaque() calls actually emit 8 + round_up(netid_len, 4) + round_up(addr_len, 4) b...
