CVE-2026-72218

A flaw was found in the Linux kernel's lockd component. A reference count leak occurs when nlmdofopen fails on a cached file path. This prevents the file's reference count from returning to zero, causing a resource leak. Over time, this can lead to resource exhaustion and a Denial of Service DoS...

In the Linux kernel, the following vulnerability has been resolved: lockd: Plug nlmfile refcount leak on cached nlmdofopen failure The cached-file path in nlmlookupfile reaches the found: label unconditionally, even when nlmdofopen fails. At that label result and file-fcount are updated before th...

CVE-2026-72219

The CVE-2026-72219 entry concerns a leak in the Linux kernel’s lockd: nlm_file allocations are not freed on nlm_do_fopen() failure. After kzalloc_obj() succeeds in nlm_lookup_file(), the new nlm_file isn’t yet in nlm_files[] when the failure path jumps to out_unlock, releasing nlm_file_mutex and ...

CVE-2026-72218

The CVE-2026-72218 entry describes a Linux kernel lockd file refcount leak in nlm_lookup_file() when nlm_do_fopen() fails on a hashed nlm_file. The cached-file path reaches the found: label unconditionally, causing *result and file->f_count to be updated before the error is returned. Wrappers ...
