Описание
Four memory leaks in the nfp_flower_spawn_phy_reprs() function in drivers/net/ethernet/netronome/nfp/flower/main.c in the Linux kernel before 5.3.4 allow attackers to cause a denial of service (memory consumption), aka CID-8572cea1461a.
A flaw was found in the way the NFP4000/NFP6000 TC Flower offload functionality in the Linux kernel handled memory cleanup on failures. This flaw allows an attacker to cause a denial of service and crash the system.
Отчет
This issue is rated as having Low impact because of the low memory conditions needed to trigger this issue.
Меры по смягчению последствий
To mitigate this issue, prevent module nfp from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
