A vulnerability was found in Linux Kernel up to 5.3.4 (Operating System). It has been classified as problematic. This affects the function sja1105_static_config_upload
of the file drivers/net/dsa/sja1105/sja1105_spi.c. The manipulation with an unknown input leads to a resource consumption vulnerability. CWE is classifying the issue as CWE-400.
