medium Tenable Cloud Security Plugin ID 464913

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: x86/cpu/hygon: Add missing
 resctrl_cpu_detect() in bsp_init helper Since 923f3a2b48bd ("x86/resctrl: Query LLC monitoring properties
 once during boot") resctrl_cpu_detect() has been moved from common CPU initialization code to the vendor-
 specific BSP init helper, while Hygon didn't put that call in their code. This triggers a division by zero
 fault during early booting stage on our machines with X86_FEATURE_CQM* supported, where
 get_rdt_mon_resources() tries to calculate mon_l3_config with uninitialized
 boot_cpu_data.x86_cache_occ_scale. Add the missing resctrl_cpu_detect() in the Hygon BSP init helper. [
