High CVSS 7.8
CVE-2026-14605
A vulnerability was identified in RT-Thread up to 5.0.2. Affected by this vulnerability is the function recvmsg in the library bsp/loongson/ls1cdev/libraries/ls1c_can.h of the component ls1c CAN Handler. Such manipulation leads to stack-based buffer overflow. Local access is required to approach this attack. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
What this means
- Exposure
- Exploitable with local access to the machine, with an ordinary user account and with no action from the victim.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Weakness
- A memory operation runs past its allocated region and corrupts neighbouring data.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
