{"id":"CVE-2026-72092","summary":"accel/amdxdna: reject command submission on devices without a submit op","details":"In the Linux kernel, the following vulnerability has been resolved:\n\naccel/amdxdna: reject command submission on devices without a submit op\n\namdxdna_cmd_submit() calls xdna-\u003edev_info-\u003eops-\u003ecmd_submit()\nunconditionally, but only aie2_dev_ops defines that callback.\naie4_vf_ops (the AIE4 SR-IOV virtual function) does not, so a user\nAMDXDNA_EXEC_CMD ioctl on an AIE4 device reaches a NULL function-pointer\ncall and oopses the kernel. AIE4 submits work through a mapped user queue\nand doorbell, not this ioctl path.\n\nReject the submission early with -EOPNOTSUPP when the device provides no\ncmd_submit op, so the shared EXEC ioctl is a clean no-op on such devices.\n\nFound by 0sec automated security-research tooling (https://0sec.ai).","modified":"2026-08-18T03:30:59.470739124Z","published":"2026-08-15T05:52:39.120Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72092.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/38953513d7313992676d4136cd425cdb70c6278e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/af7a4c2caa7a191d6e7ed33903b69f9901874cd0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f7d08603c87bae19ca3e424da5ab6d0aee81886e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72092.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72092"},{"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":"aac243092b707bb3018e951d470cc1a9bcbaba6c"},{"fixed":"af7a4c2caa7a191d6e7ed33903b69f9901874cd0"},{"fixed":"f7d08603c87bae19ca3e424da5ab6d0aee81886e"},{"fixed":"38953513d7313992676d4136cd425cdb70c6278e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72092.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.14.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72092.json"}}],"schema_version":"1.9.0"}
