A flaw was found in the Linux kernel's twl4030_charger driver. When the driver's remove function is called, it fails to properly cancel pending worker tasks. This oversight allows a worker to attempt to access memory that has already been deallocated, leading to a use-after-free vulnerability. A local attacker could potentially exploit this to cause a denial of service.
