That is the size of the reused\nreply buffer, not the number of bytes actually received.\n\nA truncated reply can therefore pass ceph_decode_need() and decode the\nsecond u64 from stale tail bytes left in the buffer by an earlier\nmessage, causing an uninitialized memory read.\n\nUse msg->front.iov_len as the receive-side decode boundary, matching\nother libceph reply handlers and limiting decoding to the bytes that\nwere actually read from the wire.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H","score":8.6},"cwes":["CWE-125"],"references":["https://git.kernel.org/stable/c/0d934c934ec746d53fc7e4f53239792647bbae63","https://git.kernel.org/stable/c/1307028f082756bf453e1889aee9983d30643a4b","https://git.kernel.org/stable/c/340e0386aa39da181015bee38f309018c335ce16","https://git.kernel.org/stable/c/4e7ebfaa0d14cf50e44041bfde38070d6dbc019f","https://git.kernel.org/stable/c/72a35070fcefa229b1b031aa7482ad3788e18f07"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-68433","score":0.00364,"percentile":0.29987,"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).
