Integer underflow in Linux kernel - CVE-2026-81000

Vulnerability identifier: #VU149394

CSH Severity: Low

CVSS v4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-81000

CWE-ID: CWE-191

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to write packet data outside allocated memory.

The vulnerability exists due to an integer underflow in TUN and TAP interface handling in tun_get_user() when processing an oversized headroom request propagated by an OVS port. A local user can configure an OVS port to propagate an oversized headroom request to a TUN or TAP device to write packet data outside allocated memory.
