CVE-2026-93199

A flaw was found in the Linux kernel's I3C master driver. The i3cmastersearchi3cdevduplicate function, which is designed to identify duplicate I3C target devices, could incorrectly identify the I3C master controller itself as a duplicate. This occurs because the function matches the controller's...

CVE-2026-93202

A flaw was found in the i3c master driver of the Linux kernel. This vulnerability occurs due to recursive locking during device registration, where the system attempts to acquire the same lock multiple times. A local attacker could potentially trigger this condition, leading to a system deadlock...

CVE-2026-93200

A flaw was found in the Linux kernel's i3c master driver. This use-after-free vulnerability occurs because sysfs attribute callbacks can attempt to access memory that has already been deallocated. An attacker could potentially exploit this to cause system instability or a denial of service...

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...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: i3c: mipi-i3c-hci: An error is now reported instead of using BUGON in IBI DMA setup. Certainly, a condition where dmagetcachealignment is defined with a value greater than 256 during driver initialization is not a reason for...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: i3c: master: Fixed an error where “free initdynaddr” was not executed at i3cmasterputi3caddrs. If dev-boardinfo && dev-boardinfo-initdynaddr ^^^ This check for “initdynaddr” was corrected. i3cbussetaddrslotstatus&master-bus,...

CVE-2026-19185

The system-call verifier for i3cdoccc in drivers/i3c/i3chandlers.c validated the outer struct i3ccccpayload, the broadcast ccc.data buffer and the targets.payloads array, but did not validate the per-target data buffers those array elements point at. Each struct i3cccctargetpayload carries its ow...

CVE-2026-19185

In Zephyr RTOS builds with CONFIG_USERSPACE, a vulnerability exists in the i3c_do_ccc() system call handler within drivers/i3c/i3c_handlers.c. The system-call verifier fails to validate per-target data buffers, allowing an unprivileged user-mode thread with I3C controller access to provide arbitr...

SUSE CVE-2026-93283

In the Linux kernel, the following vulnerability has been resolved: i3c: master: Fix deviceregister error path When deviceregister fails in i3cmasterregisternewi3cdevs, putdevice is called to drop the reference taken by deviceregister. That drops the last reference, so the device's release callba...

CVE-2026-98018

A flaw was found in the Linux kernel. A race condition in the Management Component Transport Protocol MCTP I3C driver occurs when device discovery releases a lock prematurely while a bus is simultaneously removed. A local user could exploit this synchronization flaw to access freed memory,...
