CVE-2026-24928
📋 TL;DR
This CVE describes an out-of-bounds write vulnerability in a file system module that could allow attackers to write data beyond allocated memory boundaries. Successful exploitation could affect service confidentiality, potentially exposing sensitive information. The vulnerability affects Huawei products and requires local access or specific conditions to exploit.
💻 Affected Systems
- Huawei products (specific models not detailed in provided reference)
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise leading to data exfiltration, privilege escalation, or denial of service through memory corruption.
Likely Case
Information disclosure or limited data corruption affecting specific services using the vulnerable file system module.
If Mitigated
Minimal impact with proper memory protection mechanisms and access controls in place.
🎯 Exploit Status
Out-of-bounds write vulnerabilities typically require specific conditions and knowledge of memory layout. CVSS 5.8 suggests moderate exploit complexity.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in provided information
Vendor Advisory: https://consumer.huawei.com/en/support/bulletin/2026/2/
Restart Required: Yes
Instructions:
1. Visit Huawei security advisory page. 2. Identify affected products and versions. 3. Download and apply recommended patches. 4. Restart affected systems. 5. Verify patch application.
🔧 Temporary Workarounds
Restrict file system access
linuxLimit access to vulnerable file system modules through permissions and access controls
chmod 600 /path/to/vulnerable/module
setfacl -m u:root:rw /path/to/vulnerable/module
Enable memory protection
linuxActivate ASLR and other memory protection mechanisms
sysctl -w kernel.randomize_va_space=2
🧯 If You Can't Patch
- Implement strict access controls and least privilege principles for file system operations
- Monitor system logs for unusual file system activity and memory access patterns
🔍 How to Verify
Check if Vulnerable:
Check Huawei advisory for affected product versions and compare with installed versions
Check Version:
Check product-specific version command (varies by Huawei product)
Verify Fix Applied:
Verify patch version matches Huawei's recommended fixed version and test file system operations
