CVE-2024-36973

HIGH

Linux Kernel 6.1-6.1.94, 6.2-6.6.34, 6.7-6.9.5 - Use-After-Free in pci1xxxx Auxiliary Bus Probe Error Handling

Title source: llm
STIX 2.1

Description

In the Linux kernel, the following vulnerability has been resolved: misc: microchip: pci1xxxx: fix double free in the error handling of gp_aux_bus_probe() When auxiliary_device_add() returns error and then calls auxiliary_device_uninit(), callback function gp_auxiliary_device_release() calls ida_free() and kfree(aux_device_wrapper) to free memory. We should't call them again in the error handling path. Fix this by skipping the redundant cleanup functions.
