CVE-2019-19080

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.3.4

Description The issue is related to the nfp flower spawn phy reprs() function in the Linux kernel, which is associated with an uncontrolled resource consumption. This can be exploited by a remote attacker to cause a denial of service, specifically through memory consumption. The function is located in drivers/net/ethernet/netronome/nfp/flower/main.c.

Recommendations For Linux kernel versions prior to 5.3.4, update to version 5.3.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the nfp flower spawn phy reprs() function to minimize the risk of exploitation.
