CVE-2019-19076: Canonical Ubuntu Linux

Medium severity, CVSS 5.9. EPSS: 3.2% chance of exploitation in the next 30 days.

A memory leak in the nfp_abm_u32_knode_replace() function in drivers/net/ethernet/netronome/nfp/abm/cls.c in the Linux kernel before 5.3.6 allows attackers to cause a denial of service (memory consumption), aka CID-78beef629fd9. NOTE: This has been argued as not a valid vulnerability. The upstream commit 78beef629fd9 was reverted

Affected products

• Canonical Ubuntu Linux: version 18.04 only; version 19.04 only
• Linux Linux Kernel: before 5.3.6 (fixed in 5.3.6)
• Red Hat Enterprise Linux: version 8.0 only
