Buffer overflow in Linux kernel - CVE-2020-25211

Vulnerability identifier: #VU51545

CSH Severity: Low

CVSS v4: 6.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2020-25211

CWE-ID: CWE-119

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to crash the system.

The vulnerability exists due to a boundary error within the ctnetlink_parse_tuple_filter() function in net/netfilter/nf_conntrack_netlink.c. A local user can inject conntrack netlink configuration, trigger buffer overflow and crash the kernel or force usage of incorrect protocol numbers.
