Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ext4: replace BUG_ON with proper error handling in ext4_read_inline_folio<br />
<br />
Replace BUG_ON() with proper error handling when inline data size<br />
exceeds PAGE_SIZE. This prevents kernel panic and allows the system to<br />
continue running while properly reporting the filesystem corruption.<br />
<br />
The error is logged via ext4_error_inode(), the buffer head is released<br />
to prevent memory leak, and -EFSCORRUPTED is returned to indicate<br />
filesystem corruption.
