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 5.10, 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-2026-93199

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...

CVE-2026-97515

A flaw was found in the Linux kernel's I3C Improved Inter-Integrated Circuit master driver. On affected hardware, when a target device on the bus holds the data line low, the controller triggers an interrupt feedback loop during recovery attempts. This issue creates an interrupt storm that can...

CVE-2026-93283

A flaw was found in the Linux kernel's I3C Improved Inter-Integrated Circuit master subsystem. This issue can result in a Denial of Service DoS caused by a system crash. When device registration fails, the driver frees the device object but fails to clear internal pointers referencing the freed...

CVE-2026-97515

In the Linux kernel, the following vulnerability has been resolved: i3c: master: svc: Prevent IRQ storm from false SLVSTART on NPCM845 On NPCM845, when a target on the I3C bus gets stuck holding SDA low, the controller reports a false Master Request MR in-band interrupt event. The driver handles...

The driver handles...

CVE-2026-93283 i3c: master: Fix device_register() error path

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-2026-93283 i3c: master: Fix device_register() error path

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-2026-93283

The Linux kernel contains a vulnerability in the i3c master driver related to the device_register() error path. When device_register() fails within i3c_master_register_new_i3c_devs(), the subsequent call to put_device() drops the final reference, triggering i3c_device_release() and freeing the i3...

PT-2026-98134

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the I3C master driver for NPCM845 where a target on the I3C bus holding the SDA line low causes the controller to report a false Master Request MR in-band interrupt...

PT-2026-97970

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the i3c master component where the error path for device register is handled incorrectly within the i3c master register new i3c devs function. When device register...

In the Linux kernel, the following vulnerability has been resolved: i3c: master: svc: Prevent IRQ storm from false SLVSTART on NPCM845 On NPCM845, when a target on the I3C bus gets stuck holding SDA low, the controller reports a false Master Request MR in-band interrupt event. The driver handles...

Linux Kernel Security Vulnerabilities

Versions of the Linux kernel prior to 6.18.53 contain security vulnerabilities. This vulnerability arises from the i3c master svc driver, which incorrectly sets the SLVSTART interrupt status bit when handling false master requests on the NPCM845 chip. This can lead to a feedback loop and an IRQ...
