SUSE Cryptsetup Moderate Keyring Issues Fix Advisory 2026-22645-1

## This update for cryptsetup fixes the following issues: Changes in cryptsetup: * Fix for (bsc#1270254) to avoid undesired pinning of all volume keys (via the thread keyring) through the caller's credentials when the kernel opens a file. This is due to the refactoring in kernel commit a28d893eb327 ("md: port block device access to file") that accidentally causes the caller's thread keyring to be kept alive long beyond the caller's lifetime, the kernel part is tracked in (bsc#1270252). * Add keyring key type. [b6fb6fc0] * Load volume keys in intermediary keyring linked in thread keyring. [413a3dd0] * Use unique intermediary keyring name per device. [04ef07a7] * Add regression tests.
