In the Linux kernel, the following vulnerability has been resolved:

partitions: mac: fix handling of bogus partition table

Fix several issues in partition probing:

  • The bailout for a bad partoffset must use put_dev_sector(), since the preceding read_part_sector() succeeded.
  • If the partition table claims a silly sector size like 0xfff bytes (which results in partition table entries straddling sector boundaries), bail out instead of accessing out-of-bounds memory.
  • We must not assume that the partition table contains proper NUL termination - use strnlen() and strncmp() instead of strlen() and strcmp().
