CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a NULL pointer dereference in nfp_cpp_resource_find() and nfp_resource_try_acquire() when opening a resource with a matching resource-table entry after mutex allocation fails. A local user can trigger resource acquisition to cause a denial of service.

This issue was identified through static analysis and confirmed by manual source review.
