CVE-2019-18807 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Two memory leaks in the sja1105_static_config_upload() function in drivers/net/dsa/sja1105/sja1105_spi.c in the Linux kernel before 5.3.5 allow attackers to cause a denial of service (memory consumption) by triggering static_config_buf_prepare_for_upload() or sja1105_inhibit_tx() failures, aka CID-68501df92d11.. EPSS estimates a 2.57% chance of exploitation in the next 30 days.
