In versions 5.5.2, 5.4.3, 5.3.4, 5.2.6, and 5.1.6, a use-after-free vulnerability was reported in the BLE provisioning transport (protocomm_ble) layer. The issue can be triggered by a remote BLE client while the device is in provisioning mode. The vulnerability occurred when provisioning was stopped with keep_ble_on = true. In this configuration, internal protocomm_ble state and GATT metadata were freed while the BLE stack and GATT services remained active. Subsequent BLE read or write callbacks dereferenced freed memory, allowing a connected or newly connected client to trigger invalid memory acces. This issue has been patched in versions 5.5.3, 5.4.4, 5.3.5, 5.2.7, and 5.1.7."}],"source":{"advisory":"GHSA-h7r3-gmg9-xjmg","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-02-04T19:22:43.554589Z","id":"CVE-2026-25507","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-02-04T19:24:17.464Z"}}]}}
