Name of the Vulnerable Software and Affected Versions ovs versions v0.90.0 through v2.5.0

Description The issue is related to a heap buffer over-read in flow.c, caused by an unsafe comparison in the minimasks function. This could lead to access to an unmapped region of memory, resulting in software crashes, memory modification, and possible remote execution.

Recommendations For ovs versions v0.90.0 through v2.5.0, update to a version outside of this range to resolve the issue. As a temporary workaround, consider restricting access to the flow.c component to minimize the risk of exploitation.
