CVE-2026-93200 i3c: master: Fix use-after-free of master->this

In the Linux kernel, the following vulnerability has been resolved: i3c: master: Fix use-after-free of master-this sysfs attribute callbacks for the master controller device dereference master-this. However, master-this is freed in i3cmasterdetachfreedevs before the master device itself is...

CVE-2026-93199

Linux kernel i3c master driver contains a logic flaw in the function i3c_master_search_i3c_dev_duplicate(). The function searches the I3C bus for another device sharing the same PID as a reference device, but can incorrectly match master->this—the I3C controller itself. Since the controller is...

CVE-2026-93200

CVE-2026-93200 affects the Linux kernel's i3c (Improved Inter-chip) master controller driver. The root cause is a use-after-free of the master->this pointer: it is freed in i3c_master_detach_free_devs() before the master device itself is released, yet sysfs attribute callbacks still dereferenc...

CVE-2026-90386

This Linux kernel vulnerability affects the DesignWare I3C master driver (drivers/i3c/master/dw-i3c-master.c:905). On an empty I3C bus, the ENTDAA (Enhanced Dynamic Address Assignment) command assigns no devices, causing cmd->rx_len to equal master->maxdevs. The resulting GENMASK() index be...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: i3c: master: mipi-i3c-hci: Fixed a kernel panic when accessing DATdata. The i3cmasterbusinit function may attach the I2C devices before the I3C bus initialization. In this case, the DAT allocentry will be used before the DAT init...

CVE-2026-80951

A flaw was found in the Linux kernel's I3C master driver. A malicious I3C device could exploit this by sending an In-Band Interrupt IBI payload that exceeds the allocated slot size. This can lead to an out-of-bounds write into the IBI pool, potentially causing memory corruption and system...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - i3c: master: adi: initialize the lock before enabling interrupts adii3cmasterprobe requests the IRQ and unmasks REGIRQPENDINGCMDR before the controller's IBI...

CVE-2026-80953

A flaw was found in the Linux kernel's i3c master driver. A race condition exists where the adii3cmasterprobe function requests an interrupt and unmasks a register before a critical lock xferqueue.lock is properly initialized. This allows a pending interrupt to attempt to acquire an uninitialized...

CVE-2026-80952

A flaw was found in the Linux kernel's i3c master component. During device unregistration, a race condition can occur where the device descriptor is prematurely cleared. This can lead to an information leak, exposing kernel stack contents in the generated modalias. Additionally, this flaw could...
