Detailsinfo

A vulnerability was found in Linux Kernel up to 6.9.7. It has been declared as critical. Affected by this vulnerability is the function svc_pool_stats_start of the component nfsd. The manipulation with an unknown input leads to a null pointer dereference vulnerability. The CWE definition for the vulnerability is CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. As an impact it is known to affect availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: nfsd: initialise nfsd_info.mutex early. nfsd_info.mutex can be dereferenced by svc_pool_stats_start() immediately after the new netns is created. Currently this can trigger an oops. Move the initialisation earlier before it can possibly be dereferenced.

The advisory is shared at git.kernel.org. This vulnerability is known as CVE-2024-42078 since 07/29/2024. Technical details are known, but no exploit is available.

Upgrading to version 6.9.8 eliminates this vulnerability. Applying the patch 7e8b94045bc7/e0011bca603c is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.

The vulnerability is also documented in the vulnerability database at CERT Bund (WID-SEC-2024-1722). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
