CVE-2026-43352
7.8 · HIGHOverview
CVE-2026-43352 is a high-severity vulnerability affecting linux linux_kernel. It was published on May 8, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
i3c: mipi-i3c-hci: Correct RING_CTRL_ABORT handling in DMA dequeue
The logic used to abort the DMA ring contains several flaws:
1. The driver unconditionally issues a ring abort even when the ring has
already stopped.
2. The completion used to wait for abort completion is never
re-initialized, resulting in incorrect wait behavior.
3. The abort sequence unintentionally clears RING_CTRL_ENABLE, which
resets hardware ring pointers and disrupts the controller state.
4. If the ring is already stopped, the abort operation should be
considered successful without attempting further action.
Fix the abort handling by checking whether the ring is running before
issuing an abort, re-initializing the completion when needed, ensuring that
RING_CTRL_ENABLE remains asserted during abort, and treating an already
stopped ring as a successful condition.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
