Subject: zram NULL pointer dereference (zs_malloc)
Date: Thu, 15 Oct 2020 12:11:39 +0200	[thread overview]
Message-ID: <2f2dd548-c79f-a398-6d11-1d616ec8c57d@gmail.com> (raw)


[-- Attachment #1.1.1: Type: text/plain, Size: 475 bytes --]

I found a serious bug about kernel NULL pointer dereference when using 
zram (in my case zram+btrfs) that makes system unstable and usually ends 
in a forced unclean reboot like powering off power source.

This issue is present since >5.8.0 version (this one seems not affected) 
and still present in 5.9.0 and reported in 
https://bugzilla.kernel.org/show_bug.cgi?id=209153

Since this issue seems major enough, can someone please review this issue?


Thanks.
