Operationally, ranked in the top 11.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2022-29145 is a denial-of-service vulnerability in .NET and Visual Studio that stems from uncontrolled resource consumption, tracked under CWE-400. It carries a CVSS 3.1 base score of 7.5 reflecting network attackability with low complexity and no required privileges or user interaction, resulting in high availability impact while leaving confidentiality and integrity unaffected.
An unauthenticated remote attacker can send specially crafted requests to affected .NET or Visual Studio components, exhausting resources and rendering the service unavailable. Exploitation requires no authentication or user assistance and can be performed over the network.
Microsoft security advisories recommend applying the updates listed in the MSRC guidance for the affected .NET and Visual Studio versions. Corresponding package updates have been published for Fedora to remediate the issue in those distributions.
The EPSS score reached a modest peak of 0.0620 before receding to the current value of 0.0416, indicating limited and non-persistent exploitation interest after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Limiting concurrent sessions directly prevents uncontrolled resource consumption by capping the number of active sessions per user or account.
Analysis identifies uncontrolled resource consumption indicative of denial-of-service or abuse attempts.
Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption.
Updated contingency plans include current procedures to detect, contain, and recover from resource exhaustion, limiting an attacker's ability to sustain impact from uncontrolled consumption.
Alternate site allows resumption of operations if resource exhaustion at the primary site is exploited to cause unavailability.
Alternate telecommunications services enable resumption of essential functions when primary services become unavailable due to uncontrolled resource consumption.
The team can analyze and respond to resource exhaustion incidents, reducing the impact of attacks that exploit uncontrolled consumption weaknesses.
Timely maintenance support and spare parts enable rapid recovery from failures induced by uncontrolled resource consumption, shortening the impact window of denial-of-service attacks.
