{"id":"AZL-96333","summary":"CVE-2026-74557 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: libiscsi: Fix stale-data leak into the SCSI sense buffer\n\niscsi_scsi_cmd_rsp() copies the sense data of a SCSI Response from the\ntarget-supplied data segment.  The segment carries a 2-byte sense length\nfollowed by the sense bytes, so it must hold 2 + senselen bytes, but the\nbounds check only requires datalen \u003e= senselen:\n\n\tsenselen = get_unaligned_be16(data);\n\tif (datalen \u003c senselen)\n\t\tgoto invalid_datalen;\n\tmemcpy(sc-\u003esense_buffer, data + 2,\n\t       min_t(uint16_t, senselen, SCSI_SENSE_BUFFERSIZE));\n\nA target that returns a SCSI Response whose datalen equals senselen\n(with senselen \u003c= SCSI_SENSE_BUFFERSIZE) makes the memcpy() from data +\n2 read up to two bytes past the received data.  Those bytes are stale\nconn-\u003edata contents and end up in the command's sense buffer, which is\nreturned to userspace.\n\nAccount for the 2-byte sense length prefix in the check.","modified":"2026-08-30T05:26:50Z","published":"2026-08-15T13:18:01Z","upstream":["CVE-2026-74557"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74557"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-96333.json"}}],"schema_version":"1.9.0"}
