In versions 2023.01 and prior, an attacker can send a crafted frame which is forwarded by the device. During encoding of the packet a NULL pointer dereference occurs. This crashes the device leading to denial of service. A patch is available at pull request 19678. There are no known workarounds."}], "lastModified": "2023-06-06T16:35:11.990", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:riot-os:riot:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E3ECD3F7-1DD5-430A-B5E7-50FDFE044CF7", "versionEndIncluding": "2023.01"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
