RDMA/rxe: Validate pad and ICRC before payload_size() in rxe_rcv
CVE-2026-46043 is a vulnerability related to the RDMA/rxe component where validation of pad and ICRC fields before calculating payload_size() in the rxe_rcv function is required. The provided information does not include detailed technical specifics, exploitation methods, or impact scenarios. There is no CVSS score assigned, and no known exploits in the wild have been reported. No patch or remediation details are provided, and the vendor advisory content is not included. The affected products include Microsoft and Azure Linux 3. 0 versions. Due to the lack of detailed impact and remediation data, the severity is assessed based on the nature of the vulnerability involving input validation in a kernel component.
AI Analysis
Technical Summary
This vulnerability involves the RDMA/rxe driver component in Microsoft and Azure Linux 3.0, where pad and ICRC fields are not validated before the payload_size() function is called in rxe_rcv. This could potentially lead to incorrect processing of RDMA packets. No further technical details, exploitation information, or patch status are provided in the available data.
Potential Impact
The impact details are not explicitly described in the provided information. Since the vulnerability concerns validation in a kernel-level RDMA driver, potential impacts could include denial of service or memory corruption, but these are not confirmed. No known exploits have been reported, and no CVSS score is assigned.
Mitigation Recommendations
Patch status is not yet confirmed — check the Microsoft Security Response Center advisory for current remediation guidance. No vendor advisory content or patch links are provided in the data. Until official guidance is available, monitor vendor channels for updates.
