CVE-2026-72454

The CVE-2026-72454 issue affects the Linux kernel i3c/mipi-i3c-hci path. A race in i3c_hci_addr_to_dev() occurs because it traverses bus->devs.i3c (protected by bus.lock) while the IRQ handler cannot take the lock, risking use-after-free or crashes during concurrent device add/remove. The fix ...

CVE-2026-72454 i3c: mipi-i3c-hci: Fix race in i3c_hci_addr_to_dev()

In the Linux kernel, the following vulnerability has been resolved: i3c: mipi-i3c-hci: Fix race in i3chciaddrtodev i3chciaddrtodev walks bus-devs.i3c, which is protected by bus.lock rwsem. However, it is invoked from the MIPI I3C HCI IRQ handler, which cannot take bus.lock. This allows concurrent...
