CVE-2026-43281

CVE-2026-43281 affects the Linux kernel mailbox subsystem. The flaw is an out-of-bounds access in fw_mbox_index_xlate() that can occur when #mbox-cells is

CVE-2026-43281 mailbox: Prevent out-of-bounds access in fw_mbox_index_xlate()

In the Linux kernel, the following vulnerability has been resolved: mailbox: Prevent out-of-bounds access in fwmboxindexxlate Although it is guided that mbox-cells must be at least 1, there are many instances of mbox-cells = ; in the device tree. If that is the case and the corresponding mailbox...

CVE-2026-43275

In the Linux kernel, a race condition in the UFS core driver can occur during system suspend when Runtime Power Management (RPM) level is zero. The driver previously bypassed flushing the exception-event handling work in this state, risking illegal host-controller access after entering deep power...
