Description

CVE-2025-71120 affecting package kernel for versions less than 6.6.121.1-1

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.

Affected software

AZL-74628 is recorded against 1 package.

  • kernel (fixed in 6.6.121.1-1)
