二、漏洞分析结构反馈
影响性分析说明：
A stack based out-of-bounds write flaw was found in the netfilter subsystem in the Linux kernel. If the expression length is a multiple of 4 (register size), the nft_exthdr_eval family of functions writes 4 NULL bytes past the end of the regs argument, leading to stack corruption and potential information disclosure or a denial of service.
