Description
A flaw was found in the Linux kernel's binder component. A race condition in the binder_add_freeze_work() function, caused by a temporary drop of a lock, allows binder_deferred_release() to modify internal data structures. This can lead to an out-of-bounds read, which a local attacker could exploit to potentially disclose sensitive information or cause a system crash, resulting in a denial of service.
