Memory leak in Linux kernel - CVE-2026-93071

Vulnerability identifier: #VU150959

CSH Severity: Low

CVSS v4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-93071

CWE-ID: CWE-401

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local privileged user to cause a denial of service.

The vulnerability exists due to improper resource cleanup in the bcm2835-unicam driver when handling driver initialization failures or device removal. A local privileged user can cause the driver to enter an error or removal path to leak allocated asynchronous subdevice connection resources and cause a denial of service.

The leak was detected after module removal.
