Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> btrfs: fix iteration of extrefs during log replay<br /> <br /> At __inode_add_ref() when processing extrefs, if we jump into the next<br /> label we have an undefined value of victim_name.len, since we haven&amp;#39;t<br /> initialized it before we did the goto. This results in an invalid memory<br /> access in the next iteration of the loop since victim_name.len was not<br /> initialized to the length of the name of the current extref.<br /> <br /> Fix this by initializing victim_name.len with the current extref&amp;#39;s name<br /> length.
