Description
In the Linux kernel, the following vulnerability has been resolved:
dm-ioctl: fix a possible overflow in list_version_get_info
sizeof(tt->version) is 12 bytes, but the code writes 16 bytes into the output buffer - info->vers->version[0], info->vers->version[1], info->vers->version[2] and info->vers->next. This can cause buffer overflow.
Fix this buffer overflow by replacing "sizeof(tt->version)" with "sizeof(struct dm_target_versions)".
