{"id":"CVE-2026-105753","summary":"vLLM: Mirrored multimodal IPC caches desync after a rejected request — a later request reusing the same media hash trips a receiver assertion in the engine core","details":"vLLM is an inference and serving engine for large language models. Prior to 0.28.0, the default mirrored multimodal LRU cache can commit a media hash in the frontend sender cache during multimodal rendering and before engine admission, while the engine receiver cache never receives the payload if that request is rejected. A later request reusing the same media hash causes MultiModalProcessorSenderCache to send no payload and MultiModalReceiverCache to reach an assertion with the message \"Expected a cached item,\" producing a shared-service availability failure. This issue is fixed in version 0.28.0.","aliases":["GHSA-ph3r-5jfg-f84f"],"modified":"2026-10-06T10:45:46.600660596Z","published":"2026-10-05T22:37:19.633Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-617"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105753.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105753.json"},{"type":"FIX","url":"https://github.com/vllm-project/vllm/commit/396204230423b7cc6798300926b8fa30190d26a9"},{"type":"FIX","url":"https://github.com/vllm-project/vllm/pull/46747"},{"type":"FIX","url":"https://github.com/vllm-project/vllm/pull/51897"},{"type":"WEB","url":"https://github.com/vllm-project/vllm/releases/tag/v0.28.0"},{"type":"ADVISORY","url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-ph3r-5jfg-f84f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105753"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/vllm-project/vllm","events":[{"introduced":"0"},{"fixed":"2cf0a6915ce544dc493a0990f2ea38d81601128a"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.28.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.28.0rc2","v0.28.0rc1","v0.27.2rc0","v0.26.1rc0","v0.25.0","v0.23.1rc0","v0.22.1rc0","v0.21.1rc0","v0.20.2rc0","v0.20.1rc0","v0.19.2rc0","v0.19.1rc0","v0.18.2rc0","v0.18.1rc0","v0.17.2rc0","v0.18.0rc0","v0.17.1rc0","v0.17.0rc0","v0.16.1rc0","v0.16.0rc1","v0.15.2rc0","v0.16.0rc0","v0.15.0rc1","v0.14.0rc1","v0.14.0rc0","v0.13.0rc1","v0.11.1","v0.11.1rc6","v0.11.1rc5","v0.11.1rc4","v0.11.1rc3","v0.11.1rc2","v0.11.1rc1","v0.11.1rc0","v0.11.0rc1","v0.10.2rc2","v0.10.2rc1","v0.10.1rc1","v0.10.0rc2","v0.10.0","v0.10.0rc1","v0.9.2rc1","v0.9.1rc2","v0.9.1","v0.9.1rc1","v0.9.0","v0.8.4","v0.8.3rc1","v0.8.2","v0.8.1","v0.8.0rc2","v0.8.0rc1","v0.7.3","v0.7.2","v0.7.1","v0.7.0","v0.6.6.post1","v0.6.6","v0.6.5","v0.6.4.post1","v0.6.4","v0.6.3.post1","v0.6.3","v0.6.2","v0.6.1.post2","v0.6.1.post1","v0.6.1","v0.6.0","v0.5.5","v0.5.4","v0.5.3.post1","v0.5.3","v0.5.2","v0.5.1","v0.5.0.post1","v0.5.0","v0.4.3","v0.4.2","v0.4.1","v0.4.0.post1","v0.4.0","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.7","v0.2.6","v0.2.5","v0.2.4","v0.2.3","v0.2.2","v0.2.1","v0.2.0","v0.1.7","v0.1.6","v0.1.5","v0.1.4","v0.1.3","v0.1.2","v0.1.1","v0.1.0","submission"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-105753.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
