CVE-2019-19055

Published: 18 November 2019

** DISPUTED ** A memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering nl80211hdr_put() failures, aka CID-1399c59fa929. NOTE: third parties dispute the relevance of this because it occurs on a code path where a successful allocation has already occurred.

From the Ubuntu security team

It was discovered that the netlink-based 802.11 configuration interface in the Linux kernel did not 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
