CVE-2026-72494: Linux

Critical severity, CVSS 9.8. EPSS: 0.6% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Replace waitqueue and flag with completion The driver previously used a waitqueue along with an explicit request_done flag, but without proper barriers around request_done. An earlier patch by Gui-Dong Han <hanguidong02@gmail.com> attempted to fix this by adding the missing memory barriers. Rather than adding the barriers, this patch replaces the waitqueue+flag with a completion, which is designed for this exact purpose.

Affected products

• Linux Linux: from 5.14, before 6.18.53 (fixed in 6.18.53); from 6.19, before 7.1.5 (fixed in 7.1.5)
