AnalysisCVE.org

In the Linux kernel, the following vulnerability has been resolved:

net/packet: clear RX owner on VNET header error

Commit 61fad6816fc1 ("net/packet: tpacket_rcv: avoid a producer race condition") added rx_owner_map and made tpacket_rcv() claim a V1 or V2 ring slot before converting the virtio-net header. If the conversion fails, the drop path leaves the slot claimed.

With a one-frame TPACKET_V2 ring, an unsupported UDP GSO packet leaves the only slot unavailable, so the ring also drops the next valid packet.

Clear the ownership bit on this error path. TPACKET_V3 already clears its block state here.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
