Last modified
CVE-2019-18806 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. A memory leak in the ql_alloc_large_buffers() function in drivers/net/ethernet/qlogic/qla3xxx.c in the Linux kernel before 5.3.5 allows local users to cause a denial of service (memory consumption) by triggering pci_dma_mapping_error() failures, aka CID-1acb8f2a7a9f.. EPSS estimates a 0.35% chance of exploitation in the next 30 days.
