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.
Regards
ChenYu

Based on fixes for 4.9 reported by Debian, CVE-2021-3347 is now fixed for 4.4 by 6510e4a2d04f33e4bfd221760faab23e55d8772b..46358277b2da868763517f79aa0ac25ce78c4f68 inclusive. 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.

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.

Details unknown So the fix for these three are a firmware update. However to use the newer firmware, a kernel patch [1] is required. Not sure how we should mark this in our repository... ignore or fixed by said patch?
