Description

A flaw was found in the Linux kernel's gpib module. This use-after-free vulnerability allows a local attacker to trigger a condition where memory is accessed after it has been freed. By concurrently calling specific ioctl handlers, an attacker could cause a system crash, leading to a denial of service, or potentially execute arbitrary code with elevated privileges.
