Hi!

Six new issues this week:
- CVE-2020-12362, CVE-2020-12363, CVE-2020-12364:
CVEs from Intel Advisory affecting Intel Graphics Driver. Details
unknown
It seems there's more for the intel graphics, but it is not mentioned
in our repository. OTOH trailer there that these are rather old
issues, fixed in 5.5...
Looks like CVE-2020-0544 and CVE-2020-0521 are for Windows. Debian lists
them as such [1][2]. Seems the Intel advisory directly refers to Linux
drivers by kernel version. Any other version string likely refers to
the Windows drivers.
