A vulnerability in the Linux kernel's sunrpc subsystem causes a null pointer dereference when processing a zero-length checksum. Specifically, in the function xdr_stream_decode_opaque_auth(), a zero-length checksum leads to checksum.data being set to NULL, which triggers a null pointer dereference in gss_krb5_verify_mic_v2(). This issue has been resolved by ensuring checksum.len is not less than the required minimum XDR_UNIT. Join the discussion | GCVE Database | 11/12/2025, 12:30:27 UTC Added: 07/30/2026, 15:50:46 UTC |
In the Linux kernel, the following vulnerability has been resolved: sunrpc: fix null pointer dereference on zero-length checksum In xdr_stream_decode_opaque_auth(), zero-length checksum.len causes checksum.data to be set to NULL. This triggers a NPD when accessing checksum.data in gss_krb5_verify_mic_v2(). This patch ensures that the value of checksum.len is not less than XDR_UNIT.
