Received Received - Intake

Memory Corruption in Linux Kernel Crypto Subsystem

Publication date: 2026-08-26

Last updated on: 2026-08-26

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: crypto: qce - fix error path in devm_qce_register_algs If ops->register_algs() fails, the error path repeatedly calls the same ops->unregister_algs() from the failed registration. Use the loop index to unregister the previously registered algorithms instead.

Executive Summary

This vulnerability is in the Linux kernel's crypto subsystem, specifically in the Qualcomm Crypto Engine (QCE) driver. When registering cryptographic algorithms fails, the error handling code incorrectly calls the unregister function repeatedly for the same failed operation instead of cleaning up only the successfully registered algorithms.

Impact Analysis

This could lead to system instability or crashes during cryptographic operations if the error path is triggered. It may cause resource leaks or improper cleanup of cryptographic algorithms in the kernel.

Mitigation Strategies

Update the Linux kernel to the latest patched version to resolve the crypto QCE error path issue. Check your distribution's security advisories for kernel updates addressing CVE-2026-80565.
