DescriptionNVD

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

ext4: replace BUG_ON with proper error handling in ext4_read_inline_folio

Replace BUG_ON() with proper error handling when inline data size exceeds PAGE_SIZE. This prevents kernel panic and allows the system to continue running while properly reporting the filesystem corruption.

The error is logged via ext4_error_inode(), the buffer head is released to prevent memory leak, and -EFSCORRUPTED is returned to indicate filesystem corruption.
