not properly validate status lengths in messages received from an access
point, leading to a buffer overflow. A physically proximate attacker
controlling an access point could use this to construct messages that could
possibly result in arbitrary code execution. (CVE-2020-12654)

It was discovered that memory contents previously stored in
microarchitectural special registers after RDRAND, RDSEED, and SGX EGETKEY
read operations on Intel client and Xeon E3 processors may be briefly
exposed to processes on the same or different processor cores. A local
attacker could use this to expose sensitive information. (CVE-2020-0543)");
