CVE-2026-64191

A flaw was found in the Linux kernel's i2c-stub driver. A local user with access to the /dev/i2c- device can exploit this vulnerability by issuing an I2C System Management Bus SMBus input/output control ioctl command with a specially crafted block transfer length. This invalid length can cause th...

CVE-2026-64171

A flaw was found in the Linux kernel's i2c Tegra module. This vulnerability occurs when a mutex lock fails, leading to a power management PM runtime reference leak. This leak prevents the affected device from entering runtime suspend, which can lead to increased power consumption or other resourc...

CVE-2026-64205

In the Linux kernel, the following vulnerability has been resolved: i2c: i801: fix hardware state machine corruption in error path A severe livelock and subsequent Hung Task panic were observed in the i2c-i801 driver during concurrent Fuzzing. The crash is caused by an unconditional hardware...

CVE-2026-64205

Summary: CVE-2026-64205 affects the Linux kernel i2c-i801 driver, where an unconditional hardware register cleanup in the error path could corrupt the SMBus hardware state machine during concurrent fuzzing, causing livelock and a Hung Task panic. Root cause: on i801_check_pre() failure (e.g., -EB...
