In the Linux kernel, the following vulnerability has been resolved: dm-integrity: fix leaking uninitialized kernel memory If hash size is less than… (CVE-2026-72101)
A vulnerability in the Linux kernel's dm-integrity feature caused uninitialized kernel memory to be leaked when the hash size was smaller than the device's tuple size. The issue was due to a bug where the code intended to zero the remaining space did not function correctly. This vulnerability has been resolved by a code fix that ensures proper zeroing of the memory.
AI Analysis
Technical Summary
The Linux kernel's dm-integrity module had a flaw where, if the hash size was less than the device's tuple size, the remaining space was not properly zeroed due to a bug. This resulted in leaking uninitialized kernel memory. The vulnerability was addressed by a commit that fixes the zeroing operation to prevent memory leakage.
Potential Impact
The vulnerability could lead to leakage of uninitialized kernel memory, which may expose sensitive information from kernel memory. No information about active exploitation or further impact is provided.
Mitigation Recommendations
A fix has been implemented in the Linux kernel to correct the zeroing behavior in dm-integrity. Users should apply the official kernel updates that include this fix once available. Patch status is not explicitly confirmed in the provided data; therefore, check the vendor advisory for current remediation guidance.
