How to fix?

Upgrade SLES:15.7 kernel-livepatch-6_4_0-150700_53_90-default to version 1-150700.15.3.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6_4_0-150700_53_90-default package and not the kernel-livepatch-6_4_0-150700_53_90-default package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

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

ACPICA: Fix NULL pointer dereference in acpi_ns_custom_package()

acpi_ns_custom_package() unconditionally dereferences the first element of the package to read the _BIX version number, without checking for NULL:

if ((*Elements)-&gt;Common.Type != ACPI_TYPE_INTEGER)

When firmware returns a _BIX package whose first element is an unresolvable reference, ACPICA evaluates that entry to NULL. acpi_ns_remove_null_elements() does not strip NULL entries for ACPI_PTYPE_CUSTOM packages (fixed-position format would break if elements were shifted), so acpi_ns_custom_package() sees the NULL and causes a crash.

Add a NULL check for the first element (version field) before dereferencing it. The caller then receives AE_AML_OPERAND_TYPE instead of crashing.
