CVE-2026-45916

A flaw was found in the Linux kernel's sbs-battery power supply driver. A race condition exists where an interrupt can occur after the power_supply handle has been freed but before the interrupt handler is unregistered. This can lead to the interrupt handler attempting to use a freed power_supply handle, resulting in a system crash or silent memory corruption. A similar race condition during probe can also lead to using an uninitialized power_supply handle.
