- Summary
- irqchip/realtek-rtl: Fix refcount leak in map_interrupts
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
irqchip/realtek-rtl: Fix refcount leak in map_interrupts
offindnodebyphandle() returns a node pointer with refcount incremented, we should use ofnodeput() on it when not need anymore. This function doesn't call ofnodeput() in error path. Call ofnodeput() directly after ofpropertyread_u32() to cover both normal path and error path.
