- Summary
- genirq/irqdesc: Prevent use-after-free in irq_find_at_or_after()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
genirq/irqdesc: Prevent use-after-free in irq_find_at_or_after()
irq_find_at_or_after() dereferences the interrupt descriptor which is returned by mt_find() while neither holding sparse_irq_lock nor RCU read lock, which means the descriptor can be freed between mt_find() 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:
