Change History

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

drivers/perf: hisi: hns3: Actually use devm_add_action_or_reset()

pci_alloc_irq_vectors() allocates an irq vector. When devm_add_action()
fails, the irq vector is not freed, which leads to a memory leak.

Replace the devm_add_action with devm_add_action_or_reset to ensure
the irq vector can be destroyed when it fails.
