CVE-2019-19055: Canonical Ubuntu Linux

Medium severity, CVSS 5.5. EPSS: 0.4% chance of exploitation in the next 30 days.

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

Affected products

• Canonical Ubuntu Linux: version 18.04 only; version 19.04 only; version 19.10 only
• Fedoraproject Fedora: version 30 only; version 31 only
• Linux Linux Kernel: up to and including 5.3.11
