- Summary
- ext4: use memtostr_pad() for s_volume_name
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ext4: use memtostrpad() for svolume_name
As with the other strings in struct ext4superblock, svolumename is not NUL terminated. The other strings were marked in commit 072ebb3bffe6 ("ext4: add nonstring annotations to ext4.h"). Using strscpy() isn't the right replacement for strncpy(); it should use memtostr_pad() instead.
