Subject: lz4 hc buffer overflow
Date: Sun, 10 Mar 2024 20:00:24 -0400 [thread overview]
Message-ID: <js2vmwcgwyx5kxq3csunc3piwkpfsebg3u2zewok6iis5wgn2e@eyy4fzryskj7> (raw)
reference https://github.com/koverstreet/bcachefs/issues/658
It looks like something is off with the bounds checking in LZ4 HC; I
haven't dug too deep yet. Never saw this with regular LZ4.
Anyone know anything? Are we missing a fix from the userspace library?
