CVE-2026-64135

A flaw was found in the Linux kernel's pmbus/adm1266 driver. This vulnerability occurs because the adm1266nvmemreadblackbox function uses a small, fixed-size buffer to read data from an I2C Inter-Integrated Circuit device. If the device sends more data than the buffer can hold, it causes a buffer...

CVE-2026-64083

A flaw was found in the Linux kernel's pmbus/adm1266 driver within the hwmon subsystem. The adm1266gpioget and adm1266gpiogetmultiple functions fail to validate the length of responses from I2C block-read operations. A local user or a malicious I2C Inter-Integrated Circuit slave device can exploi...
