Infinite loop in HTTP/2 transport when given bad SETTINGS_MAX_FRAME_SIZE in net/http/internal/http2 in golang.org/x/net
CVE-2026-33814 is a vulnerability involving an infinite loop in the HTTP/2 transport implementation within the net/http/internal/http2 package of golang. org/x/net. This occurs when the component receives a malformed SETTINGS_MAX_FRAME_SIZE value. The vulnerability affects Microsoft products including Azure Linux 3. 0 and golang versions used by Microsoft. No CVSS score or detailed impact metrics are provided, and there is no indication of known exploits in the wild. Patch or remediation status is not confirmed from the available data.
AI Analysis
Technical Summary
This vulnerability is an infinite loop triggered by a bad SETTINGS_MAX_FRAME_SIZE parameter in the HTTP/2 transport code of golang.org/x/net's net/http/internal/http2 package. It affects Microsoft products including Azure Linux 3.0 and golang components. The infinite loop could potentially cause denial of service by making the HTTP/2 transport unresponsive. No CVSS score or detailed vendor advisory information is available to confirm patch status or exploitation details.
Potential Impact
The primary impact is a potential denial of service condition caused by an infinite loop in the HTTP/2 transport when processing malformed SETTINGS_MAX_FRAME_SIZE values. There is no evidence of active exploitation. The vulnerability could affect services relying on the vulnerable golang HTTP/2 implementation, potentially causing service disruption.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround information is provided in the available data. Until a patch is available, consider monitoring for malformed HTTP/2 frames and applying any vendor recommendations once published.
