the Linux kernel during device removal. A privileged or physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2020-27820)

It was discovered that the Bluetooth subsystem in the Linux kernel
contained a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2021-3640)

Likang Luo discovered that a race condition existed in the Bluetooth
subsystem of the Linux kernel, leading to a use-after-free vulnerability. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2021-3752)

It was discovered that the SCTP protocol implementation in the Linux kernel
did not properly verify VTAGs in some situations. A remote attacker could
possibly use this to cause a denial of service (connection disassociation).
(CVE-2021-3772)

It was discovered that the eBPF implementation in the Linux kernel
contained a race condition around read-only maps. A privileged attacker
could use this to modify read-only maps. (CVE-2021-4001)

It was discovered that the NFS server implementation in the Linux kernel
contained an out-of-bounds write vulnerability. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2021-4090)

Felix Wilhelm discovered that the KVM implementation in the Linux kernel
did not properly handle exit events from AMD Secure Encrypted
Virtualization-Encrypted State (SEV-ES) guest VMs. An attacker in a guest
VM could use this to cause a denial of service (host kernel crash) or
possibly execute arbitrary code in the host kernel. (CVE-2021-4093)

Lin Ma discovered that the NFC Controller Interface (NCI) implementation in
the Linux kernel contained a race condition, leading to a use-after-free
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2021-4202)

It was discovered that the AMD Radeon GPU driver in the Linux kernel did
not properly validate writes in the debugfs file system. A privileged
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2021-42327)

Luo Likang discovered that the FireDTV Firewire driver in the Linux kernel
