MariaDB 11.4.7 crash with "malloc(): unsorted double linked list corrupted" (signal 6) during normal operation

(This is my first bug report here, apologies in advance for any mistakes I make)

MariaDB 11.4.7 crashed with a fatal malloc(): unsorted double linked list corrupted error and signal 6. This caused the server to hang during shutdown (status: "Shutdown in progress"), required a manual kill -9, and forced crash recovery on restart.

The system was stable for over 8 hours before the crash occurred. Load was moderate (~30% CPU) and no configuration changes had recently been made.

This appears to be a glibc memory corruption issue potentially triggered by InnoDB or internal memory management routines. There is no indication of query abuse or external corruption.
