CVE-2019-15926
Published: 4 September 2019
An issue was discovered in the Linux kernel before 5.2.3. Out of bounds access exists in the functions ath6kl_wmi_pstream_timeout_event_rx and ath6kl_wmi_cac_event_rx in the file drivers/net/wireless/ath/ath6kl/wmi.c.
From the Ubuntu Security Team
It was discovered that the Atheros mobile chipset driver in the Linux kernel did not properly validate data in some situations. An attacker could use this to cause a denial of service (system crash).
