Detailsinfo

A vulnerability has been found in Linux Kernel up to 6.11.6 and classified as critical. This vulnerability affects the function cleanup_async_copy. The manipulation of the argument async_copies with an unknown input leads to a initialization vulnerability. The CWE definition for the vulnerability is CWE-665. The product does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used. As an impact it is known to affect availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: NFSD: Initialize struct nfsd4_copy earlier Ensure the refcount and async_copies fields are initialized early. cleanup_async_copy() will reference these fields if an error occurs in nfsd4_copy(). If they are not correctly initialized, at the very least, a refcount underflow occurs.

The advisory is available at git.kernel.org. This vulnerability was named CVE-2024-50241 since 10/21/2024. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 216030 (EulerOS 2.0 SP12 : kernel (EulerOS-SA-2025-1176)), which helps to determine the existence of the flaw in a target environment.
