CVE-2026-80953 i3c: master: adi: initialize the lock before enabling interrupts

In the Linux kernel, the following vulnerability has been resolved: i3c: master: adi: initialize the lock before enabling interrupts adii3cmasterprobe requests the IRQ and unmasks REGIRQPENDINGCMDR before the controller's IBI state, transfer queue list and transfer queue lock are initialized. A...

CVE-2026-80953

CVE-2026-80953 is a race condition in the Linux kernel's ADI i3c master driver . The function adi_i3c_master_probe() requests the IRQ and unmasks REG_IRQ_PENDING_CMDR before the controller's transfer queue lock (xferqueue.lock) and IBI state are initialized. A pending CMDR interrupt can therefore...

CVE-2026-80952

In the Linux kernel, the following vulnerability has been resolved: i3c: master: Fix info leak and UAF in device unregister path i3cmasterunregisteri3cdevs clears i3cdev-dev-desc before calling deviceunregister. During deviceunregister, devicedel emits a KOBJREMOVE uevent and unbinds the driver...

CVE-2026-80952

CVE-2026-80952 affects the Linux kernel i3c master component. The root cause is a race condition in i3c_master_unregister_i3c_devs(), which clears the device descriptor (i3cdev->dev->desc) before device_unregister() completes. During the unbind process, i3c_device_uevent() and a racing moda...

CVE-2026-80951

CVE-2026-80951 is an out-of-bounds write in the Linux kernel's i3c master svc driver. The function svc_i3c_master_handle_ibi() reads IBI payloads from the RX FIFO, but its loop is bounded by the hardware FIFO size rather than the per-slot max_payload_len . When a device sends more bytes than the ...

CVE-2026-80950

A use-after-free vulnerability exists in the Linux kernel's Renesas I3C driver . The driver uses an asynchronous data-transfer model: it enqueues a transfer struct and waits for completion. If a transfer times out , the waiting thread frees the struct. If an interrupt then fires, the interrupt ha...
