Overview

CVE-2026-46102 is a high-severity vulnerability. It was published on May 27, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

net: strparser: fix skb_head leak in strp_abort_strp()

When the stream parser is aborted, for example after a message assembly timeout,

it can still hold a reference to a partially assembled message in

strp->skb_head.

That skb is not released in strp_abort_strp(), which leaks the partially

assembled message and can be triggered repeatedly to exhaust memory.

Fix this by freeing strp->skb_head and resetting the parser state in the

abort path. Leave strp_stop() unchanged so final cleanup still happens in

strp_done() after the work and timer have been synchronized.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
