AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-58346 is a medium-severity vulnerability found in the Wi-Fi drivers of multiple Samsung Exynos System on Chip (SoC) models. The issue occurs due to an unbounded memory allocation when writing to the procfs interface at `/proc/driver/unifi0/send_addts`. This means that an attacker can cause the system to allocate excessive amounts of kernel memory without limits.
This flaw leads to kernel memory exhaustion, which can disrupt normal system operations.
How can this vulnerability impact me? :
The primary impact of this vulnerability is that it can cause a denial of service (DoS) condition. By exploiting the unbounded memory allocation, an attacker can exhaust kernel memory resources, potentially causing the affected device to become unresponsive or crash.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability involves unbounded memory allocation via a write operation to the procfs interface at /proc/driver/unifi0/send_addts, leading to kernel memory exhaustion.
To detect potential exploitation or attempts, monitoring kernel logs for memory exhaustion or related errors is recommended.
You can check the status of the procfs interface and monitor write operations to /proc/driver/unifi0/send_addts.
- Use dmesg or journalctl to look for kernel memory exhaustion or related warnings: `dmesg | grep -i memory` or `journalctl -k | grep -i memory`
- Monitor the /proc/driver/unifi0/send_addts file for unusual write activity, for example, using auditd rules or inotify tools.
- Check system memory usage and kernel resource consumption with commands like `free -m`, `vmstat`, or `top` to identify abnormal memory depletion.
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting access to the vulnerable procfs interface to prevent unauthorized write operations.
Limiting user permissions and ensuring only trusted processes or users can write to /proc/driver/unifi0/send_addts can reduce risk.
Monitoring system logs for signs of exploitation attempts and applying any available patches or updates from Samsung as soon as they are released is critical.
If possible, temporarily disabling or restricting the Wi-Fi driver component until a patch is applied may help prevent exploitation.
