ODP_ZEROBASED : ODP_NOT_NEEDED);\n\n* The code modified by this patch is guarded by IS_ERR(trans_private),\n  where trans_private is assigned as per the previous point in this analysis.\n\n  The only implementation of get_mr that I could locate is rds_ib_get_mr()\n  which can return an ERR_PTR if the conn (4th) argument is NULL.\n\n* ret is set to PTR_ERR(trans_private).\n  rds_ib_get_mr can return ERR_PTR(-ENODEV) if the conn (4th) argument is NULL.\n  Thus ret may be -ENODEV in which case the code in question will execute.\n\nConclusion:\n* cp may be NULL at the point where this patch adds a check;\n  this patch does seem to address a possible bug","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-476"],"references":["https://git.kernel.org/stable/c/62fc3357e079a07a22465b9b6ef71bb6ea75ee4b","https://git.kernel.org/stable/c/6794090c742008c53b344b35b021d4a3093dc50a","https://git.kernel.org/stable/c/92309bed3c5fbe2ccd4c45056efd42edbd06162d","https://git.kernel.org/stable/c/bcd46782e2ec3825d10c1552fcb674d491cc09f9","https://git.kernel.org/stable/c/cbaac2e5488ed54833897264a5ffb2a341a9f196"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:50:30.954589733+00:00"},"epss":{"cve":"CVE-2024-35902","score":0.00223,"percentile":0.12793,"date":"2026-10-25"},"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).
