Priority
Description
An issue was discovered in net/wireless/nl80211.c in the Linux kernel
through 5.2.17. It does not check the length of variable elements in a
beacon head, leading to a buffer overflow.
Ubuntu-Description

configuration interface for the Linux kernel when handling beacon settings.
A local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code.
