Summary
CVE-2025-39795 affecting package kernel for versions less than 5.15.200.1-1
Details

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

block: avoid possible overflow for chunk_sectors check in blk_stack_limits()

In blk_stack_limits(), we check that the t->chunk_sectors value is a multiple of the t->physical_block_size value.

However, by finding the chunk_sectors value in bytes, we may overflow the unsigned int which holds chunk_sectors, so change the check to be based on sectors.
