CVE-2026-68328

The CVE relates to the Linux kernel nfp subsystem. Specifically, nfp_cpp_resource_find() allocates a CPP mutex handle for a matching resource-table entry, and nfp_resource_try_acquire() passes that handle to nfp_cpp_mutex_trylock(). If nfp_cpp_mutex_alloc() fails and returns NULL, the resource lo...
