In the Linux kernel, the following vulnerability has been resolved: block:
add check that partition length needs to be aligned with block size Before
calling add partition or resize partition, there is no check on whether the
length is aligned with the logical block size. If the logical block size of
the disk is larger than 512 bytes, then the partition size maybe not the
multiple of the logical block size, and when the last sector is read,
bio_truncate() will adjust the bio size, resulting in an IO error if the
size of the read command is smaller than the logical block size.If
integrity data is supported, this will also result in a null pointer
dereference when calling bio_integrity_free.
