CWEhttps://cwe.mitre.org/data/definitions/416.html

MariaDB Server v10.6.5 and below was discovered to contain an use-after-free in the component Item_args::walk_arg, which is exploited via specially crafted SQL statements.

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
