CVE-2026-72495Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Avoid repeated requests to allocate WC pages Applications can request multiple WC pages for the same ucontext. As of now, only 1 WC page per ucontext is supported. Add a lock to avoid concurrent access and a check to fail repeated requests. Also, if the mmap entry insert fails for the WC, free the Doorbell page index mapped for the WC page. This could lead to concurrent access issues and potentially result in a denial of service due to resource exhaustion. Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-770. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 9.
