{"id":"CVE-2026-72060","summary":"net: ethernet: ti: icssg: guard PA stat lookups","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ethernet: ti: icssg: guard PA stat lookups\n\nicssg_ndo_get_stats64() unconditionally calls emac_get_stat_by_name()\nwith FW PA stat names regardless of whether the PA stats block is\npresent on the hardware.  emac_get_stat_by_name() already guards the\nPA stats lookup with `if (emac-\u003eprueth-\u003epa_stats)`; when that pointer\nis NULL the lookup falls through to netdev_err() and returns -EINVAL.\nBecause ndo_get_stats64 is polled regularly by the networking stack\nthis produces thousands of log entries of the form:\n\n  icssg-prueth icssg1-eth end0: Invalid stats FW_RX_ERROR\n\nA secondary consequence is that the int(-EINVAL) return value is\nimplicitly widened to a near-ULLONG_MAX unsigned value when accumulated\ninto the __u64 fields of rtnl_link_stats64, silently corrupting the\nrx_errors, rx_dropped and tx_dropped counters reported by `ip -s link`.\n\nEvery other PA-aware code path in the driver is already guarded with\nthe same `if (emac-\u003eprueth-\u003epa_stats)` check.  Apply the same guard\nhere.","modified":"2026-08-18T03:31:19.253567671Z","published":"2026-08-15T05:52:15.099Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72060.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/121c5f31c3fb70d4a23e8a084f5cb8b3ec63be8d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/27b9daba50609335db6ca81e4cccf50ded21ec76"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b3763f7e22ecaa7ad79bf44bf41816d488edbcf8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72060.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72060"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0d15a26b247d25cd012134bf8825128fedb15cc9"},{"fixed":"121c5f31c3fb70d4a23e8a084f5cb8b3ec63be8d"},{"fixed":"b3763f7e22ecaa7ad79bf44bf41816d488edbcf8"},{"fixed":"27b9daba50609335db6ca81e4cccf50ded21ec76"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72060.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.16.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72060.json"}}],"schema_version":"1.9.0"}
