RDMA/mana: Validate rx_hash_key_len
Overview
Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/mana: Validate rx_hash_key_len Sashiko points out that rx_hash_key_len comes from a uAPI structure and is blindly passed to memcpy, allowing the userspace to trash kernel memory. Bounds check it so the memcpy cannot overflow.

CVSS Scores
The Common Vulnerability Scoring System is a standardized framework
for assessing the severity of vulnerabilities in software and systems.
We collect and displays CVSS scores from various sources for each CVE.
| Score | Version | Severity | Vector | Exploitability Score | Impact Score | Source |
|---|---|---|---|---|---|---|
| CVSS 3.1 | HIGH | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | ||||
| CVSS 3.1 | HIGH | 0b0ca135-0b70-47e7-9f44-1890c2a1c46c |
Solution
Validate rx_hash_key_len before memcpy to prevent kernel memory corruption.
- Apply kernel patches for RDMA/mana.
- Bounds check rx_hash_key_len before memcpy.
- Update the Linux kernel to the latest version.
