Overview

CVE-2026-53102 is a medium-severity vulnerability. It was published on June 24, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

wifi: mt76: Fix memory leak after mt76_connac_mcu_alloc_sta_req()

mt76_connac_mcu_alloc_sta_req() allocates an skb which is expected to

be freed eventually by mt76_mcu_skb_send_msg(). However, currently if

an intermediate function fails before sending, the allocated skb is

leaked.

Specifically, mt76_connac_mcu_sta_wed_update() and

mt76_connac_mcu_sta_key_tlv() may fail, leading to an immediate memory

leak in the error path.

Fix this by explicitly freeing the skb in these error paths.

Commit 7c0f63fe37a5 ("wifi: mt76: mt7996: fix memory leak on

mt7996_mcu_sta_key_tlv error") made a similar change.

Compile tested only. Issue found using a prototype static analysis tool

and code review.

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.

How can CyberStrike help with CVE-2026-53102?

CyberStrike is an open-source, AI-augmented pentesting engine.
