Description
A flaw was found in the Linux kernel's binder component. This vulnerability, a Use-After-Free (UAF), occurs when oneway transactions are sent to a frozen target. Although these transactions return an error, they are still processed, allowing the transaction data to be prematurely freed. A local attacker could exploit this timing issue to access freed memory, potentially leading to privilege escalation or arbitrary code execution within the system.
