CVE-2019-18810

Published: 7 November 2019

A memory leak in the komeda_wb_connector_add() function in drivers/gpu/drm/arm/display/komeda/komeda_wb_connector.c in the Linux kernel before 5.3.8 allows attackers to cause a denial of service (memory consumption) by triggering drm_writeback_connector_init() failures, aka CID-a0ecd6fdbf5d.

From the Ubuntu security team

It was discovered that the ARM Komeda display driver for the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could use this to cause a denial of service (memory exhaustion).

Priority

Low

CVSS 3 base score: 7.5
