A fix is available — apply it.

An issue was discovered in Erlang/OTP 18.x. Erlang's generation of compiled regular expressions is vulnerable to a heap overflow. Regular expressions using a malformed extpattern can indirectly specify an offset that is used as an array index. This ordinal permits arbitrary regions within the erts_alloc arena to be both read and written to.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact total (CVSS ≥ 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
