Memory leak in Linux kernel - CVE-2026-93136

Vulnerability identifier: #VU150869

CSH Severity: Low

CVSS v4: 2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-93136

CWE-ID: CWE-401

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to cause a resource leak.

The vulnerability exists due to improper reference count management in mhi_ep_create_device() when dev_set_name() or device_add() fails during MHI device creation. A local user can trigger a device-creation error to cause a resource leak.
