Description OSIDB Bzimport 2026-08-15 06:08:25 UTC 
In the Linux kernel, the following vulnerability has been resolved:

dm-integrity: fix leaking uninitialized kernel memory

If hash size is less than device's tuple size, dm-integrity is supposed
to zero the remaining space. There was a bug in the code that zeroing
didn't work. This commit fixes it.
