How to fix?

Upgrade SLES:15.6 kernel-default-extra to version 6.4.0-150600.23.14.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default-extra package and not the kernel-default-extra package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

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.
