The index of the loop is equal to the number of\nPDOs to be updated when leaving the loop and it doesn't need to be added\none.\n\nWhen doing the power negotiation, TCPM relies on the \"nr_snk_pdo\" as\nthe size of the local sink PDO array to match the Source capabilities\nof the partner port. If the off-by-one overflow occurs, a wrong RDO\nmight be sent and unexpected power transfer might happen such as over\nvoltage or over current (than expected).\n\n\"nr_src_pdo\" is used to set the Rp level when the port is in Source\nrole. It is also the array size of the local Source capabilities when\nfilling up the buffer which will be sent as the Source PDOs (such as\nin Power Negotiation). If the off-by-one overflow occurs, a wrong Rp\nlevel might be set and wrong Source PDOs will be sent to the partner\nport. This could potentially cause over current or port resets.","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:H/A:H","score":7.8},"cwes":["CWE-193"],"references":["https://git.kernel.org/stable/c/c4128304c2169b4664ed6fb6200f228cead2ab70","https://git.kernel.org/stable/c/f3da3192cdd3fefe213390e976eec424a8e270b5","https://git.kernel.org/stable/c/c4128304c2169b4664ed6fb6200f228cead2ab70","https://git.kernel.org/stable/c/f3da3192cdd3fefe213390e976eec424a8e270b5","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/4EZ6PJW7VOZ224TD7N4JZNU6KV32ZJ53/"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:49:08.435428910+00:00"},"epss":{"cve":"CVE-2024-26995","score":0.00238,"percentile":0.14918,"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).
