CWE-ID: CWE-416 - Use After Free

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 pf1550 power supply IRQ handler when handling interrupts 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 initialized during probe.
