CVE-2026-36499

Description A missing upper-bound check in the udpif set threads() function allows an attacker with OVSDB write access to request an excessive number of handler or revalidation threads. This can lead to a denial of service (DoS) through resource exhaustion, which occurs when a system lacks the necessary memory or CPU cycles to function properly.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
