This vulnerability occurs due to improper management of delayed tasks when the device is being removed or if its initialization fails. A pending task can attempt to access memory that has already been released, leading to a use-after-free condition. This could allow a local attacker to cause the system to crash, resulting in a Denial of Service, or potentially lead to privilege escalation.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · updated 2026-09-17 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-89465.json)\n\n**kernel: power: supply: rt9455: quiesce delayed work before teardown** — rated Moderate by Red Hat.
