CVE-2019-19077

Published: 18 November 2019

A memory leak in the bnxt_re_create_srq() function in drivers/infiniband/hw/bnxt_re/ib_verbs.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering copy to udata failures, aka CID-4a9d46a9fe14.

From the Ubuntu security team

It was discovered that the Broadcom Netxtreme HCA device driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion).

Priority

Low

CVSS 3 base score: 5.5
