 * go#77413 runtime: netpollinit() incorrectly prints the error from linux.Eventfd
 * go#77438 cmd/go: CGO compilation fails after upgrading from Go 1.25.5 to 1.25.6 due to --define-variable flag in pkg-config
 * go#77531 net/smtp: expiry date of localhostCert for testing is too short

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected go1.25, go1.25-doc, go1.25-libstd and / or go1.25-race packages.
