Ilja Van Sprundel discovered that the SCTP implementation in the Linux
kernel did not properly perform size validations on incoming packets in
some situations. An attacker could possibly use this to expose sensitive
information (kernel memory). (CVE-2021-3655)

It was discovered that the AMD Cryptographic Coprocessor (CCP) driver in
the Linux kernel did not properly deallocate memory in some error
conditions. A local attacker could use this to cause a denial of service
(memory exhaustion). (CVE-2021-3744, CVE-2021-3764)

It was discovered that the NFC subsystem in the Linux kernel contained a
use-after-free vulnerability in its NFC Controller Interface (NCI)
implementation. A local attacker could possibly use this to cause a denial
of service (system crash) or execute arbitrary code. (CVE-2021-3760)

It was discovered that an integer overflow could be triggered in the eBPF
implementation in the Linux kernel when preallocating objects for stack
maps. A privileged local attacker could use this to cause a denial of
service or possibly execute arbitrary code. (CVE-2021-41864)

It was discovered that the KVM implementation for POWER8 processors in the
Linux kernel did not properly keep track if a wakeup event could be
resolved by a guest. An attacker in a guest VM could possibly use this to
cause a denial of service (host OS crash). (CVE-2021-43056)

It was discovered that the ISDN CAPI implementation in the Linux kernel
contained a race condition in certain situations that could trigger an
array out-of-bounds bug. A privileged local attacker could possibly use
this to cause a denial of service or execute arbitrary code.
(CVE-2021-43389)
