{"id":"AZL-95085","summary":"CVE-2026-68418 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/irdma: Prevent user-triggered null deref on QP create\n\nPreviously, the user QP creation path would only attempt to\npopulate iwqp-\u003eiwpbl if the user-provided req.user_wqe_bufs\nfield was non-zero. The problem is that iwqp-\u003eiwpbl is\nunconditionally dereferenced later on in irdma_setup_virt_qp.\n\nWhile there was a check for iwqp-\u003eiwpbl != NULL, this check\nwould only occur if req.user_wqe_bufs was non-zero. The end\nresult is that a user could send a zero user_wqe_bufs value\nand trigger a null ptr deref.\n\nFix this by unconditionally calling irdma_get_pbl and bailing\nif it fails, similar to the CQ and SRQ paths.","modified":"2026-08-31T05:26:27Z","published":"2026-08-10T13:20:35Z","upstream":["CVE-2026-68418"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68418"}],"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-95085.json"}}],"schema_version":"1.9.0"}
