Threats tagged 'ghsa-w9g3-rpmc-68j2'

A vulnerability in the Linux kernel's JFS filesystem driver related to improper handling of set_blocksize failures has been resolved. The issue arises because JFS uses buffer_heads, which do not handle block sizes larger than PAGE_SIZE correctly. This can cause a kernel BUG_ON condition during mounting, specifically in the folio_set_bh function on the first __bread_gfp call.
