Answer in brief
CVE-2026-45887 records a Medium severity (CVSS 5.5) vulnerability in af_unix: Fix memleak of newsk in unix_stream_connect().. 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.
CVSS is 5.5. 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: af_unix: Fix memleak of newsk in unix_stream_connect(). When prepare_peercred() fails in unix_stream_connect(), unix_release_sock() is not called for newsk, and the memory is leaked. Let's move prepare_peercred() before unix_create1().
