Any negative value for src_id (e.g. -1) trivially satisfied this check and was forwarded into z_impl_log_filter_set, where it propagated to filter_set() and ultimately to get_dynamic_filter(), which uses source_id as an unsigned index into the linker-section array &TYPE_SECTION_START(log_dynamic)[source_id].filters.\n\nAfter implicit conversion through uint32_t, an int16_t -1 becomes 0xFFFFFFFF, indexing log_dynamic far out of bounds and causing the kernel to perform an OOB read and an OOB read-modify-write (LOG_FILTER_SLOT_GET/SET) against memory adjacent to the log_dynamic section.\n\nThe written value is a constrained 3-bit log level slot within the targeted 32-bit word, but the target address is attacker-chosen (a small negative offset from log_dynamic) and the write occurs in supervisor mode following a syscall from an unprivileged user thread, providing a kernel memory-corruption / privilege-escalation primitive.\n\nThe defect is reachable on any build with CONFIG_USERSPACE=y and CONFIG_LOG_RUNTIME_FILTERING=y. Present from Zephyr v3.3.0 through v4.4.1. The fix replaces the signed bound check with an unsigned comparison: (uint32_t)src_id < log_src_cnt_get(domain_id), which correctly rejects negative inputs.", "title": "cveprojectv5 - https://raw.githubusercontent.com/CVEProject/cvelistV5/main/cves/2026/10xxx/CVE-2026-10682.json" }, { "category": "other", "text": "0.0016", "title": "EPSS" }, { "category": "other", "text": "3.4", "title": "NCSC Score" }, { "category": "other", "text": "Is related to an uncommon product vendor, Is related to (a version of) an uncommon product, There is exploit data available from source Nvd", "title": "NCSC Score top decreasing factors" } ], "product_status": { "known_affected": [ "CSAFPID-8807274", "CSAFPID-5591608", "CSAFPID-5591612", "CSAFPID-5591613", "CSAFPID-5591614", "CSAFPID-5591615", "CSAFPID-5591638", "CSAFPID-5591639", "CSAFPID-5591640", "CSAFPID-5591641", "CSAFPID-5591642", "CSAFPID-5596063", "CSAFPID-5596064", "CSAFPID-5596065", "CSAFPID-5596066", "CSAFPID-5596067", "CSAFPID-5596068", "CSAFPID-5596069", "CSAFPID-5596070", "CSAFPID-5596071", "CSAFPID-5596072", "CSAFPID-5604263", "CSAFPID-5604264", "CSAFPID-5604265", "CSAFPID-5604266", "CSAFPID-5604267", "CSAFPID-5604268", "CSAFPID-5604269", "CSAFPID-5604270", "CSAFPID-8566770", "CSAFPID-8566771", "CSAFPID-8566772", "CSAFPID-8566773", "CSAFPID-8570143", "CSAFPID-8570144", "CSAFPID-8570145", "CSAFPID-8570146", "CSAFPID-8570147", "CSAFPID-8570148", "CSAFPID-8570149", "CSAFPID-8570150", "CSAFPID-8875133", "CSAFPID-8971460" ] }, "references": [ { "category": "external", "summary": "Source - first", "url": "https://api.first.org/data/v1/epss" }, { "category": "external", "summary": "Source - osv", "url": "https://www.googleapis.com/download/storage/v1/b/osv-vulnerabilities/o/GIT%2FCVE-2026-10682.json?alt=media" }, { "category": "external", "summary": "Source - cveprojectv5", "url": "https://raw.githubusercontent.com/CVEProject/cvelistV5/main/cves/2026/10xxx/CVE-2026-10682.json" }, { "category": "external", "summary": "Source - nvd", "url": "https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-10682" }, { "category": "external", "summary": "Source - ncscclear", "url": "https://vulnerabilities.ncsc.nl/manual/CVE-2026-10682" }, { "category": "external", "summary": "Reference - cveprojectv5; nvd; osv", "url": "https://github.com/zephyrproject-rtos/zephyr/commit/56a15114c6acbab2067fe406dc3adda8608f3def" }, { "category": "external", "summary": "Reference - cveprojectv5; nvd; osv", "url": "https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-6vqh-mg7h-58qh" }, { "category": "external", "summary": "Reference - osv", "url": "https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/10xxx/CVE-2026-10682.json" }, { "category": "external", "summary": "Reference - osv", "url": "https://nvd.nist.gov/vuln/detail/CVE-2026-10682" } ], "scores": [ { "cvss_v3": { "version": "3.1", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:H", "baseScore": 6.6, "baseSeverity": "MEDIUM" }, "products": [ "CSAFPID-5591608", "CSAFPID-5591612", "CSAFPID-5591613", "CSAFPID-5591614", "CSAFPID-5591615", "CSAFPID-5591638", "CSAFPID-5591639", "CSAFPID-5591640", "CSAFPID-5591641", "CSAFPID-5591642", "CSAFPID-5596063", "CSAFPID-5596064", "CSAFPID-5596065", "CSAFPID-5596066", "CSAFPID-5596067", "CSAFPID-5596068", "CSAFPID-5596069", "CSAFPID-5596070", "CSAFPID-5596071", "CSAFPID-5596072", "CSAFPID-5604263", "CSAFPID-5604264", "CSAFPID-5604265", "CSAFPID-5604266", "CSAFPID-5604267", "CSAFPID-5604268", "CSAFPID-5604269", "CSAFPID-5604270", "CSAFPID-8566770", "CSAFPID-8566771", "CSAFPID-8566772", "CSAFPID-8566773", "CSAFPID-8570143", "CSAFPID-8570144", "CSAFPID-8570145", "CSAFPID-8570146", "CSAFPID-8570147", "CSAFPID-8570148", "CSAFPID-8570149", "CSAFPID-8570150", "CSAFPID-8807274", "CSAFPID-8875133", "CSAFPID-8971460" ] } ], "title": "CVE-2026-10682" } ] }
