Details

In the Linux kernel, the following vulnerability has been resolved:

genirq/irqdesc: Prevent use-after-free in irqfindatorafter()

irqfindatorafter() dereferences the interrupt descriptor which is returned by mtfind() while neither holding sparseirqlock nor RCU read lock, which means the descriptor can be freed between mtfind() and the dereference:

CPU0                            CPU1
desc = mt_find()
                                delayed_free_desc(desc)
irq_desc_get_irq(desc)

The use-after-free is reported by KASAN:

Guard the access with a RCU read lock section.
