Release kernel-6.12.0-211.67.1.el10_2 ALSA-2026:85321

This issue announces a kernel release containing security fixes and bug fixes across many subsystems, including SCTP, SMB, USB Type-C and memory management. Start by reviewing the listed CVEs and JIRA items; the issue does not identify source files, tests, or one change to make. Done would require coordinating and validating the full release, so this is not a bounded first contribution.
