{"id":"CVE-2026-72494","summary":"RDMA/irdma: Replace waitqueue and flag with completion","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/irdma: Replace waitqueue and flag with completion\n\nThe driver previously used a waitqueue along with an explicit\nrequest_done flag, but without proper barriers around request_done.\n\nAn earlier patch by Gui-Dong Han \u003changuidong02@gmail.com\u003e attempted\nto fix this by adding the missing memory barriers. Rather than\nadding the barriers, this patch replaces the waitqueue+flag with\na completion, which is designed for this exact purpose.","modified":"2026-08-18T03:56:43.813852766Z","published":"2026-08-15T05:57:28.280Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72494.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/bde37aed0724c0139dea177f3aae8d989b6babb1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d9c8c45e6d2f438a3c8e643ae78b59454fa0fadd"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72494.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72494"},{"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":"44d9e52977a1b90b0db1c7f8b197c218e9226520"},{"fixed":"bde37aed0724c0139dea177f3aae8d989b6babb1"},{"fixed":"d9c8c45e6d2f438a3c8e643ae78b59454fa0fadd"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72494.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.14.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72494.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
