Detailed vulnerability description
The vulnerability allows a local attacker to cause a denial of service or corrupt memory.
The vulnerability exists due to a use-after-free in the pm8916_bms_vm driver power_supply handling when handling an interrupt during device removal or probe. 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 has been registered, leading to use of an uninitialized handle.
