CVE-2026-90026Hinoki check available

Use-after-free via pending reset work

Published Sep 16, 2026 · Updated Sep 16, 2026

Use-after-free in the Qualcomm PMIC Type-C PD PHY driver in Linux 6.5 allows attackers to cause unspecified impact via unspecified vectors. The pdphy_stop() path disables the driver's IRQs but does not cancel reset_work, so work queued immediately before IRQ shutdown can execute after remove() releases the containing structure through devm. Reachability requires the Qualcomm PMIC Type-C PD PHY driver and a teardown race in which its IRQ handler queues reset work before device removal.
