Improper control of a resource through its lifetime in Linux kernel - CVE-2026-90362

Vulnerability identifier: #VU152200

CSH Severity: Low

CVSS v4: 0 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-90362

CWE-ID: CWE-664

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to cause the DSI link clock to run without necessary power backing.

The vulnerability exists due to improper power-state management in dsi_link_clk_disable_6g() when disabling DSI link clocks. A local user can trigger the DSI link clock disable path to cause the DSI link clock to run without necessary power backing.
