In the Linux kernel, the following vulnerability has been resolved:
EDAC/altera: Fix use-after-free in error paths
In both altr edac a10 device add() and altr portb setup(), the error path
freed the dci structure before releasing the devres group. Since the managed
single and double bit IRQ handlers use altdev(dci->pvt info) as their data, an
IRQ firing between freeing dci and unregistering the IRQs could dereference
the freed memory.
Release the devres group first so the managed IRQs are unregistered
before the dci structure is freed.
