Описание
An issue was discovered in the Linux kernel before 5.2.3. An out of bounds access exists in the function hclge_tm_schd_mode_vnet_base_cfg in the file drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_tm.c.
An out-of-bounds access flaw was found in the hclge_shaper_para_calc driver in the Linux kernel. Access to an array with an index higher than its maximum index will lead to an out-of-bounds access vulnerability. This could affect both data confidentiality and integrity as well as system availability.
Меры по смягчению последствий
Blacklisting the affected HCLGE driver module until a patch is available can be done using the blacklist mechanism. This will ensure the driver is not loaded at boot time. For instructions on how to black list a kernel module, please read: https://access.redhat.com/solutions/41278.
