Prior to version 2022.10, an attacker can send a crafted frame to the device resulting in a NULL pointer dereference. During forwarding of a fragment an uninitialized entry in the reassembly buffer is used. The NULL pointer dereference triggers a hard fault exception resulting in denial of service. Version 2022.10 fixes this issue. As a workaround, disable support for fragmented IP datagrams or apply the patches manually."}], "lastModified": "2023-05-03T15:44:33.400", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:riot-os:riot:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "2A1B64C3-901D-4D06-AD22-FA94E65D5024", "versionEndExcluding": "2022.10"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
