Jul 30 RESCORED — CVE-2025-71120 (Linux). CVSS 7.5 → 5.5 (NVD).
Description
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: svcauth_gss: avoid NULL deref on zero length gss_token in gss_read_proxy_verf
A zero length gss_token results in pages == 0 and in_token->pages[0]
is NULL. The code unconditionally evaluates
page_address(in_token->pages[0]) for the initial memcpy, which can
dereference NULL even when the copy length is 0. Guard the first
memcpy so it only runs when length > 0.
