Description
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.
Affected configurations
• linux linux kernel (>= 3.8 < 6.6.131)
• linux linux kernel (>= 6.7 < 6.12.80)
• linux linux kernel (>= 6.13 < 6.18.21)
• linux linux kernel (>= 6.19 < 6.19.11)
• linux linux kernel 7.0
