Hi everyone,

Six new issues this week:
- CVE-2020-12362, CVE-2020-12363, CVE-2020-12364:
CVEs from Intel Advisory affecting Intel Graphics Driver. Details unknown

- CVE-2021-20194 [bpf heap overflow] - fixed for relevant kernels
- CVE-2021-20226 [io_uring UAF] - likely a duplicate of
CVE-2020-29534, already fixed
- CVE-2021-26708 [AF_VSOCK: local priv. escalation] - fixed for relevant kernels

Additionally, CVE-2021-3347 is fixed for 4.4 and 4.9.
I still need to match patches for 4.4 against 4.9, but it looks like
the fixes are there.
Based on fixes for 4.9 reported by Debian, CVE-2021-3347 is now fixed for 4.4 by

Lee Jones just posted a few follow-up fixes for futexes for 4.9 [1]. I
wonder if they
would also be posted for 4.4.
