Use-after-free in Linux kernel - CVE-2026-90395

Vulnerability identifier: #VU151075

CSH Severity: Low

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

CVE-ID: CVE-2026-90395

CWE-ID: CWE-416

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local privileged user to access freed power supply state.

The vulnerability exists due to a use-after-free in the isp1704 charger driver's remove path when queued or running work executes during device removal. A local privileged user can cause work scheduled by USB notification or initial VBUS detection to execute after the power supply state is torn down to access freed power supply state.
