Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于ice组件未能为每个VF的FDIR过滤器数量设置限制，导致恶意VF驱动程序耗尽其他VF的资源。

Vulnerability Title
ice: Add a per-VF limit on number of FDIR filters
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ice: Add a per-VF limit on number of FDIR filters While the iavf driver adds a s/w limit (128) on the number of FDIR filters that the VF can request, a malicious VF driver can request more than that and exhaust the resources for other VFs. Add a similar limit in ice.
