Answer in brief
CVE-2026-14605 records a High severity (CVSS 7.8) vulnerability in RT-Thread ls1c CAN ls1c_can.h recvmsg stack-based overflow. The current sources do not mark it as known exploited. The current feed maps n/a/RT-Thread (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
