{"id":"CVE-2026-97435","published":"2026-09-24T17:17:21.573","lastModified":"2026-09-25T13:17:27.120","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: dsa: sja1105: flower: reject cross-chip redirect\n\ndsa_port_from_netdev() may return a valid port from a different switch\nchip. Programming another chip's port index into the local hardware\ncauses redirection to the wrong port, or an out-of-bounds access if the\nindex exceeds the local chip's port count.\n\nApply a minimal fix that adds a check to catch this case and adjusts the\nextack message. When cls->common.skip_sw is not set, the operation could\ninstead redirect to the upstream port and let the software or upstream\nswitch(es) handle the forward, but that is not addressed here.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/abd7511e12b231798332afa04ed9bee9e84f9445","tags":[]},{"url":"https://git.kernel.org/stable/c/c999cc39775381b68ed66eae57c1425452672c0f","tags":[]},{"url":"https://git.kernel.org/stable/c/cfa5274a5dc2a23b957da5dc806d2ac0c7a66af0","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
