Description Adam Mariš 2018-04-05 07:49:29 UTC
It was discovered that the netlink 802.11 configuration interface in the
Linux kernel did not properly validate some attributes passed from
userspace. A local attacker with the CAP_NET_ADMIN privilege could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code.
