Description
A flaw was found in the Linux kernel's sh: intc component. Incorrect error handling within the register_intc_controller() function can lead to a use-after-free vulnerability. This occurs when a data structure is freed but not removed from an internal list, allowing subsequent operations to access freed memory. A local attacker could potentially exploit this to achieve privilege escalation, arbitrary code execution, or cause a denial of service.
