Description
A flaw was found in the Linux kernel's Altera EDAC (Error Detection and Correction) driver. In device setup error-handling paths, driver memory is released before the associated interrupt handlers are unregistered. If an interrupt fires during this cleanup window, the handler dereferences freed memory, resulting in a kernel crash and Denial of Service (DoS).
