A flaw was found in the Linux kernel's power supply driver for the pf1550 component. A race condition during system shutdown or startup could lead to a use-after-free vulnerability. This issue allows an interrupt to access memory that has been deallocated or not yet initialized, potentially causing the system to crash or corrupt memory. This could result in a denial of service.
