| Doc Text: |
A flaw was found in PCRE2, a library for processing regular expressions. The `pcre2_jit_match` function, which handles just-in-time (JIT) compilation for regular expressions, incorrectly manages memory when processing certain inputs. This memory corruption vulnerability could allow a local attacker to cause the application to crash, leading to a denial of service, or potentially execute unauthorized code.
