{"id":"CVE-2026-72494","aliases":[],"url":"https://o3.security/vulnerability/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 <hanguidong02@gmail.com> 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.","published":"2026-08-15T05:57:28.280Z","modified":"2026-08-18T03:56:43.813852766Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"7.1.5"}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-18T03:56:43.813852766Z"}}
