CVE-2024-46697

The CVE-2024-46697 issue in the Linux kernel’s nfsd path (nfsd4_fattr_args.context) is fixed: if a goto out path executes before security label checks, an uninitialized args.context on the stack could be freed. The mitigation is to zero/initialize args.context early, preventing a use-after-free/M...
