When this happens, tps53679_identify_chip() accesses buf[ret - 1]\nwhich is buf[-1], reading one byte before the buffer on the stack.\n\nFix by changing the check from \"ret < 0\" to \"ret <= 0\", treating a\nzero-length read as an error (-EIO), which prevents the out-of-bounds\narray access.\n\nAlso fix a typo in the adjacent comment: \"if present\" instead of\nduplicate \"if\".","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","score":7.1},"cwes":["CWE-125"],"references":["https://git.kernel.org/stable/c/0e211f6aaa6a00fd0ee0c1eea5498f168c6725e6","https://git.kernel.org/stable/c/6999b4769e2a61c463158927102e8c07e3f69ba2","https://git.kernel.org/stable/c/79b7e588399bb55f4c10bea6ca41b6c3b944d2bb"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-43005","score":0.00124,"percentile":0.02098,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
