Vulnerability identifier: #VU102161

CSH Severity: Low

CVSS v4 BT: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2024-56655

CWE-ID: CWE-667

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper locking within the nf_tables_newtable(), nf_tables_rule_destroy(), nf_tables_deactivate_set(), __nft_release_basechain_now() and __nft_release_basechain() functions in net/netfilter/nf_tables_api.c. A local user can perform a denial of service (DoS) attack.
