This means\nthat operations must be atomic in order to, e.g., avoid spreading\nwrites across multiple rows. Since the shadow SRAM array is used to\nfind free rows in the hardware table, it must also be protected in\norder to avoid TOCTOU errors where multiple cores allocate the same\nrow.\n\nThis issue was detected in a situation where `mvpp2_set_rx_mode()` ran\nconcurrently on two CPUs. In this particular case the\nMVPP2_PE_MAC_UC_PROMISCUOUS entry was corrupted, causing the\nclassifier unit to drop all incoming unicast - indicated by the\n`rx_classifier_drops` counter.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":4.7},"cwes":["CWE-367"],"references":["https://git.kernel.org/stable/c/46c1e23e34c9d1eaadf37f88216d9d8ce0d0bcee","https://git.kernel.org/stable/c/5b0ae1723a7d9574ae1aee7d9cf9757a30069865","https://git.kernel.org/stable/c/96844075226b49af25a69a1d084b648ec2d9b08d","https://git.kernel.org/stable/c/b3f48a41a00d6d8d9c6fe09ae47dd21c8c1c8b03","https://git.kernel.org/stable/c/e3711163d14d02af9005e4cdad30899c565f13fb"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:11.054312287+00:00"},"epss":{"cve":"CVE-2025-22060","score":0.00159,"percentile":0.05022,"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).
