From 5.5.5 until 5.5.6, 6.0.4, and 6.1.1, the esp_tee trap entry in esp_tee_vectors_plic.S and esp_tee_vectors_clic.S saves a caller-controlled register frame through the REE-supplied stack pointer before switching to the trusted TEE stack or validating the pointer. A local unprivileged REE application can direct this machine-mode write into TEE-exclusive memory on ESP32-C5, ESP32-C6, ESP32-C61, and ESP32-H2 devices, breaking the REE/TEE isolation boundary and potentially corrupting TEE control-flow data for code execution, denial of service, or system crashes. Both secure-service ecall and interrupt entry paths contain the vulnerable ordering. This issue is fixed in version 5.5.6 and is scheduled to be fixed in versions 6.0.4 and 6.1.1.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":9.3,"severity":"critical","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793819061450,"publishedAt":1793819061450,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/espressif/esp-idf/security/advisories/GHSA-49x8-xqjg-2pjg"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/espressif/esp-idf/commit/773761abb893d43d0a5b8b75ec0a1c2cf0287d53"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/espressif/esp-idf/commit/acb7d996b07293abf591b93f4aaffa04ae6732d9"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/espressif/esp-idf/commit/b85a7b0e1449ac9aec30a0c3e3b6515725556fd1"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/espressif/esp-idf/commit/dabd37fae8d2a7b1cc71f48fce824b0b9d909a07"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/espressif/esp-idf/releases/tag/v5.5.6"}],"remediation":[],"revision":"25c213103a1fcadb4ab80085ef55c2dbbd8f693b339fc9c1867b36edec8f1418","sources":[{"modifiedAt":1793819061450,"name":"CNA: GitHub_M","retrievedAt":1793822904441,"url":"https://www.cve.org/CVERecord?id=CVE-2026-113780"}],"ssvc":null,"status":"published","title":"ESF-IDF: Unvalidated Stack Pointer at the ESP-TEE Privilege-Switch Boundary","updatedAt":1793822904441}
