一、漏洞信息
漏洞编号:CVE-2023-4244
漏洞归属组件:kernel
漏洞归属的版本:4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8,6.4.0
CVSS V3.0分值:
BaseScore:7.0 High
Vector:CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
漏洞简述:
A use-after-free vulnerability in the Linux kernel s netfilter: nf_tables component can be exploited to achieve local privilege escalation.Due to a race condition between nf_tables netlink control plane transaction and nft_set element garbage collection, it is possible to underflow the reference counter causing a use-after-free vulnerability.We recommend upgrading past commit 3e91b0ebd994635df2346353322ac51ce84ce6d8.
