CVE-2023-4881
Detail
Rejected
CVE has been marked "REJECT" in the CVE List. These CVEs are stored in the NVD, but do not show up in search results.
Current Description
Rejected reason: CVE-2023-4881 was wrongly assigned to a bug that was deemed to be a non-security issue by the Linux kernel security team.
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.
