Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: lockd: Other missing fields are set when unlocking files. The vfslockfile function expects that the struct filelock structure is fully initialized by the caller. If the flfile field is NULL after re-exporting NFSv3, an OOP err...

CVE-2026-74315

A flaw was found in the lockd component of the Linux kernel. A remote attacker can exploit this vulnerability by presenting a Network Lock Manager version 4 NLMv4 file handle shorter than expected. This causes the system to hash uninitialized bytes, leading to inconsistent file handle lookups...

CVE-2026-72219

A flaw was found in the Linux kernel's lockd component. A remote attacker can repeatedly trigger failures in the nlmdofopen function by providing specially crafted file handles that the system rejects. This vulnerability causes a memory leak, where each failed operation consumes system memory...

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...
