#VU124858 Memory leak in Linux kernel - CVE-2026-23414
Published: April 3, 2026
Vulnerability identifier: #VU124858
Vulnerability risk: Low
CVSSv4.0: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
CVE-ID: CVE-2026-23414
CWE-ID: CWE-401
Exploitation vector: Local access
Exploit availability:
No public exploit available
Vulnerable software:
Linux kernel
Linux kernel
Software vendor:
Linux Foundation
Linux Foundation
Description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to improper resource management in tls_decrypt_async_wait() and the async_hold queue when processing pending asynchronous TLS decrypt operations. A local user can trigger a partial failure during message hold handling to cause a denial of service.
This issue results in a memory leak because cloned skbs added to the async_hold queue may not be released in some fallback paths after pending AEAD operations are synchronized. No user interaction is required.
Remediation
Install security update from vendor's repository.
