CVE-2025-39795 (GCVE-0-2025-39795)

Title
block: avoid possible overflow for chunk_sectors check in blk_stack_limits()
Summary
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.
Severity
No CVSS data available.
