Description

This security bulletin contains information about 1 vulnerability.


1) Use-after-free (CVE-ID: CVE-2026-45867)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/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 attacker to cause a denial of service or corrupt memory.

The vulnerability exists due to use-after-free in the act8945a power supply IRQ handler when handling an interrupt during device probe or removal. A local attacker 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.
