Description
A flaw was found in the Linux kernel's Trusted Execution Environment (TEE) subsystem, specifically within the OP-TEE driver. This use-after-free vulnerability occurs when a client task terminates before its associated supplicant has finished processing a request. This timing issue can lead to the system attempting to access memory that has already been freed, potentially resulting in a denial of service or arbitrary code execution.
