CVE-2002-1420
openbsd openbsd: no CVSS score yet. EPSS 0.3% chance of exploitation in the next 30 days.
Integer signedness error in select() on OpenBSD 3.1 and earlier allows local users to overwrite arbitrary kernel memory via a negative value for the size parameter, which satisfies the boundary check as a signed integer, but is later used as an unsigned integer during a data copying operation.
