- Summary
- CVE-2025-39795 affecting package kernel for versions less than 6.6.104.2-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
block: avoid possible overflow for chunksectors check in blkstack_limits()
In blkstacklimits(), we check that the t->chunksectors value is a multiple of the t->physicalblock_size value.
However, by finding the chunksectors value in bytes, we may overflow the unsigned int which holds chunksectors, so change the check to be based on sectors.
