kernel: NFSv4/pNFS: reject zero-length r_addr in nfs4_decode_mp_ds_addr

A flaw was found in the Linux kernel's NFSv4/pNFS implementation. The nfs4decodempdsaddr function, responsible for decoding network address information, does not properly handle zero-length raddr opaque data. A malicious or compromised metadata server can exploit this by providing a zero-length...

CVE-2026-53391

In the Linux kernel, the following vulnerability has been resolved: NFSv4/pNFS: reject zero-length raddr in nfs4decodempdsaddr nfs4decodempdsaddr decodes the rnetid and raddr opaques of a netaddr4 from a GETDEVICEINFO multipath-DS body, then immediately calls strrchrbuf, '.' to locate the port...

CVE-2026-53391

CVE-2026-53391 affects the Linux kernel NFSv4/pNFS code. The nfs4_decode_mp_ds_addr decoder can dereference NULL when an on-wire r_addr opaque has zero length, because xdr_stream_decode_string_dup() may yield NULL and the code then calls strrchr(NULL, '.') leading to a kernel NULL pointer derefer...
