CVE-2026-89464

CVE-2026-89464 affects the Linux kernel component power: supply: twl4030_charger . The root cause is a use-after-free : the bci structure is devm-allocated, but twl4030_bci_remove() fails to cancel two workers (bci->work and bci->current_worker) that dereference it, allowing a pending worke...
