CVE-2019-16746 NOMISEC CRITICAL WORKING POC
Linux kernel <5.2.17 - Buffer Overflow
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.
CVSS 9.8
CVE-2020-36691 WRITEUP MEDIUM WRITEUP
Linux Kernel < 5.8 - Denial of Service via Unbounded Recursion in Netlink Policy
An issue was discovered in the Linux kernel before 5.8. lib/nlattr.c allows attackers to cause a denial of service (unbounded recursion) via a nested Netlink policy with a back reference.
CVSS 5.5
CVE-2021-38206 WRITEUP MEDIUM WRITEUP
Linux Kernel < 5.12.13 - Denial of Service via 802.11a Frame Injection in mac80211 Radiotap Parser
The mac80211 subsystem in the Linux kernel before 5.12.13, when a device supporting only 5 GHz is used, allows attackers to cause a denial of service (NULL pointer dereference in the radiotap parser) by injecting a frame with 802.11a rates.
