In the Linux kernel, the following vulnerability has been resolved:
ext4: xattr: fix null pointer deref in ext4rawinode()
If ext4getinodeloc() fails (e.g. if it returns -EFSCORRUPTED), iloc.bh will remain set to NULL. Since ext4xattrinodedecrefall() lacks error checking, this will lead to a null pointer dereference in ext4rawinode(), called right after ext4getinode_loc().
Found by Linux Verification Center (linuxtesting.org) with SVACE.
