Threats tagged 'ghsa-grhw-m2j5-c3v8'

A vulnerability in the Linux kernel's HPFS filesystem driver was resolved that involved improper handling of set_blocksize failures. The HPFS driver uses buffer_heads, which do not handle block sizes larger than PAGE_SIZE correctly. This flaw could cause a kernel BUG_ON condition during mounting due to an offset check failure in folio_set_bh on the first __bread_gfp call.
