CVE-2025-39795

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> block: avoid possible overflow for chunk_sectors check in blk_stack_limits()<br /> <br /> In blk_stack_limits(), we check that the t-&gt;chunk_sectors value is a<br /> multiple of the t-&gt;physical_block_size value.<br /> <br /> However, by finding the chunk_sectors value in bytes, we may overflow<br /> the unsigned int which holds chunk_sectors, so change the check to be<br /> based on sectors.
