Answer in brief
CVE-2026-68379 records a Unknown severity vulnerability in tcp: fix TIME_WAIT socket reference leak on PSP policy failure. 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: tcp: fix TIME_WAIT socket reference leak on PSP policy failure Release the TIME_WAIT socket reference and jump to discard_it upon PSP policy failure in both IPv4 and IPv6 receive paths. This prevents a memory leak of tcp_tw_bucket structures.
