CVE-2025-71120

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> SUNRPC: svcauth_gss: avoid NULL deref on zero length gss_token in gss_read_proxy_verf<br /> <br /> A zero length gss_token results in pages == 0 and in_token-&gt;pages[0]<br /> is NULL. The code unconditionally evaluates<br /> page_address(in_token-&gt;pages[0]) for the initial memcpy, which can<br /> dereference NULL even when the copy length is 0. Guard the first<br /> memcpy so it only runs when length &gt; 0.
