The current CPU sync starts at\ndma_addr and only covers rx_bytes + MVPP2_MH_SIZE bytes, which syncs the\nunused headroom and misses the same number of bytes at the packet tail.\n\nOn non-coherent DMA systems this can leave the CPU reading stale cache\ncontents for the end of the received frame.\n\nUse dma_sync_single_range_for_cpu() with MVPP2_SKB_HEADROOM as the range\noffset so the sync covers the Marvell header and packet data actually\nwritten by hardware.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L","score":8.6},"cwes":["CWE-682"],"references":["https://git.kernel.org/stable/c/180235600934bef6add3be637c296d6cf3272e67","https://git.kernel.org/stable/c/19f8bc139e9b149d1e5bf75ae761d1bb8dd3e7d8","https://git.kernel.org/stable/c/23548007b3c66d628fc7d6b80d1e23be04ea10d9","https://git.kernel.org/stable/c/60412bdd1b2576659eac23a23d2d9ff96228a643","https://git.kernel.org/stable/c/a13199fa224e9f776f4005d5037df03aa9ea8f37"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2026-53217","score":0.00384,"percentile":0.32256,"date":"2026-10-26"},"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).
