In the Linux kernel, the following vulnerability has been resolved:
ACPICA: check null return of ACPI_ALLOCATE_ZEROED() in acpi_db_convert_to_package()
ACPICA commit 4d4547cf13cca820ff7e0f859ba83e1a610b9fd0
ACPI_ALLOCATE_ZEROED() may fail, elements might be NULL and will cause
NULL pointer dereference later.
[ rjw: Subject and changelog edits ]
A flaw was found in the Linux kernel's Advanced Configuration and Power Interface (ACPI) Component Architecture (ACPICA). A missing check for a null return value from a memory allocation function (ACPI_ALLOCATE_ZEROED()) in the acpi_db_convert_to_package() function can lead to a null pointer dereference. This vulnerability could allow a local attacker to cause a system crash, resulting in a denial of service.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
