CVE-2026-43275
4.7 · MEDIUMOverview
CVE-2026-43275 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 6, 2026 and has a CVSS 3.1 base score of 4.7 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 4.7, rated MEDIUM. 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:
scsi: ufs: core: Flush exception handling work when RPM level is zero
Ensure that the exception event handling work is explicitly flushed during
suspend when the runtime power management level is set to UFS_PM_LVL_0.
When the RPM level is zero, the device power mode and link state both
remain active. Previously, the UFS core driver bypassed flushing exception
event handling jobs in this configuration. This created a race condition
where the driver could attempt to access the host controller to handle an
exception after the system had already entered a deep power-down state,
resulting in a system crash.
Explicitly flush this work and disable auto BKOPs before the suspend
callback proceeds. This guarantees that pending exception tasks complete
and prevents illegal hardware access during the power-down sequence.
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.
