  - In ovs versions v0.90.0 through v2.5.0 are vulnerable to heap buffer over-read in flow.c. An unsafe
    comparison of minimasks function could lead access to an unmapped region of memory. This vulnerability
    is capable of crashing the software, memory modification, and possible remote execution. (CVE-2022-32166)
