Description

This security bulletin contains information about 1 vulnerability.


1) Use-after-free (CVE-ID: CVE-2026-46270)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to cause a denial of service or corrupt memory.

The vulnerability exists due to a use-after-free in the rt9455 charger driver interrupt handling path when handling interrupts during device probe or removal. A local user can trigger a race condition to cause a denial of service or corrupt memory.

The issue can also occur if an interrupt fires before the power_supply handle is registered, leading to use of an uninitialized handle in power_supply_changed().
