CVE-2023-53672

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> btrfs: output extra debug info if we failed to find an inline backref<br /> <br /> [BUG]<br /> Syzbot reported several warning triggered inside<br /> lookup_inline_extent_backref().<br /> <br /> [CAUSE]<br /> As usual, the reproducer doesn&amp;#39;t reliably trigger locally here, but at<br /> least we know the WARN_ON() is triggered when an inline backref can not<br /> be found, and it can only be triggered when @insert is true. (I.e.<br /> inserting a new inline backref, which means the backref should already<br /> exist)<br /> <br /> [ENHANCEMENT]<br /> After the WARN_ON(), dump all the parameters and the extent tree<br /> leaf to help debug.
