Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)->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.
 (CVE-2026-97446)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.739.5 or later.
