MariaDB through 10.5.9 allows attackers to trigger a convert_const_to_int use-after-free when the BIGINT data type is used.

Weakness

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
