CVE-2022-49885

CVE-2022-49885 is a Linux kernel vulnerability in ACPI APEI where ghes_estatus_pool_init() can overflow due to signed integer math during len calculation (len += (num_ghes * GHES_ESOURCE_PREALLOC_MAX_SIZE)). The root cause is using int for num_ghes, which can overflow and cause subsequent vmalloc...
