{"id":"CVE-2026-73108","state":"PUBLISHED","title":"RustDesk < 1.4.7 Uncontrolled Memory Allocation DoS via BytesCodec","description":"RustDesk versions before 1.4.7 contain an uncontrolled speculative memory allocation vulnerability in BytesCodec. Before authentication, the decoder trusts the payload length encoded in a four-byte frame header and reserves that amount before receiving the payload. A crafted header can request up to 1,073,741,823 bytes of capacity, allowing unauthenticated attackers to use concurrent TCP connections to cause memory exhaustion and denial of service. The fix caps header-triggered speculative preallocation at 256 KiB.","publishedAt":"2026-08-26T13:00:29.283Z","updatedAt":"2026-10-01T15:20:30.744Z","severity":{"score":8.7,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["rustdesk rustdesk"],"affected":[{"vendor":"rustdesk","product":"rustdesk","packageURL":"pkg:github/rustdesk/rustdesk","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"1.4.7","versionType":"semver"}],"repo":"https://github.com/rustdesk/rustdesk"}],"references":["https://github.com/rustdesk/rustdesk/releases/tag/1.4.7","https://github.com/rustdesk/hbb_common/commit/547da54b4ee58eed47163fbd47edb4639e3d88de","https://github.com/rustdesk/rustdesk/commit/518296f2570d107ad416f29ade5fcce3177f4115","https://www.vulncheck.com/advisories/rustdesk-uncontrolled-memory-allocation-dos-via-bytescodec"],"weaknesses":["CWE-770"],"ingestedAt":"2026-10-29T20:12:58.252Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/73xxx/CVE-2026-73108.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-73108","state":"PUBLISHED","datePublished":"2026-08-26T13:00:29.283Z","dateUpdated":"2026-10-01T15:20:30.744Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-08-10T21:04:42.166Z"},"containers":{"cna":{"title":"RustDesk < 1.4.7 Uncontrolled Memory Allocation DoS via BytesCodec","descriptions":[{"lang":"en","value":"RustDesk versions before 1.4.7 contain an uncontrolled speculative memory allocation vulnerability in BytesCodec.
