{"apiVersion":"1.0","identifier":"CVE-2026-99154","description":"In the Linux kernel, the following vulnerability has been resolved: scsi: libiscsi: Reject a negative task index from parse_pdu_itt A transport that implements parse_pdu_itt hands libiscsi an index taken from the PDU, and both lookups bound it from above only: if (i >= session->cmds_max) i and cmds_max are both int, so a negative index passes and session->cmds[i] is read from before the array. be2iscsi produces one. beiscsi_parse_pdu() assigns the raw tag, *index = (int)itt; and beiscsi_complete_pdu() forwards an unsolicited NOP-In from the hardware async ring without replacing its ITT, so the value is the target-s. It also reports the session-s own age rather than the one in the tag, which leaves the age comparison in iscsi_verify_itt() with nothing to reject. Bound the index from below in both lookups.","publishedAt":"2026-10-28T11:17:35","lastModifiedAt":"2026-10-31T13:17:57","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-99154","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00514,"riskScore":1.03,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-99154","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-99154","en":"https://www.redsauce.net/en/cves/CVE-2026-99154","fr":"https://www.redsauce.net/fr/cves/CVE-2026-99154","pt":"https://www.redsauce.net/pt/cves/CVE-2026-99154","de":"https://www.redsauce.net/de/cves/CVE-2026-99154","sk":"https://www.redsauce.net/sk/cves/CVE-2026-99154","el":"https://www.redsauce.net/el/cves/CVE-2026-99154"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-99154"}}
