{"id":"AZL-102099","summary":"CVE-2026-93103 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/hfi1: Preserve unit 0 on allocation failure\n\nhfi1_free_devdata() assumes that the device was inserted into the unit\ntable and unconditionally erases dd-\u003eunit. If xa_alloc_irq() fails, the\nzero-initialized unit remains zero, so full cleanup can remove an\nunrelated device from index 0.\n\nRelease only the rdmavt allocation and return immediately while the unit\ntable has not acquired the device.","modified":"2026-09-18T14:17:49.650138418Z","published":"2026-09-17T17:18:04Z","upstream":["CVE-2026-93103"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93103"}],"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-102099.json"}}],"schema_version":"1.9.0"}
