Linux Kernel 6.0-6.1.92, 6.2-6.6.32, 6.7-6.8.11, 6.9-6.9.2 - Use-After-Free in PCI IRQ Vector Allocation

Title source: llm
STIX 2.1

Description

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.

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