Answer in brief
CVE-2026-68349 records a Unknown severity vulnerability in wifi: carl9170: fix buffer overflow in rx_stream failover path. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: wifi: carl9170: fix buffer overflow in rx_stream failover path The failover continuation in carl9170_rx_stream() copies the full tlen from the second USB transfer instead of capping at rx_failover_missing bytes. When both transfers are near maximum size, the total exceeds the 65535-byte failover SKB, triggering skb_over_panic. Limit the copy size to the missing byte count.
