Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6_4_0-150600_23_7-default package and not the kernel-livepatch-6_4_0-150600_23_7-default 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:

spi: mchp-pci1xxx: Fix a possible null pointer dereference in pci1xxx_spi_probe

In function pci1xxxx_spi_probe, there is a potential null pointer that may be caused by a failed memory allocation by the function devm_kzalloc. Hence, a null pointer check needs to be added to prevent null pointer dereferencing later in the code.

To fix this issue, spi_bus->spi_int[iter] should be checked. The memory allocated by devm_kzalloc will be automatically released, so just directly return -ENOMEM without worrying about memory leaks.
