CVE-2019-19055

Status Candidate

Overview

** 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.

Ubuntu Security Notice 4225-2 - USN-4225-1 fixed vulnerabilities in the Linux kernel for Ubuntu 19.10. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 19.10 for Ubuntu 18.04 LTS. It was discovered that a heap-based buffer overflow existed in the Marvell WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

Ubuntu Security Notice 4226-1 - Michael Hanselmann discovered that the CIFS implementation in the Linux kernel did not sanitize paths returned by an SMB server. An attacker controlling an SMB server could use this to overwrite arbitrary files. It was discovered that a heap-based buffer overflow existed in the Marvell WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
