Linux kernel Hardware Monitoring Driver Use-After-Free

The vulnerability in the adm1266gpiogetmultiple function within the drivers/hwmon/pmbus/adm1266.c file of the Linux kernel’s hardware monitoring driver is related to buffer overflow conditions. Exploitation of this vulnerability could allow an attacker to compromise the confidentiality, integrity...

Linux kernel Device Monitoring Driver Use-After-Free

The vulnerability in the adm1266nvmemreadblackbox function within the drivers/hwmon/pmbus/adm1266.c file of the Linux kernel-based hardware monitoring driver is related to a stack buffer overflow. Exploitation of this vulnerability could allow an attacker to compromise the confidentiality,...

Linux kernel Device Monitoring Driver Use-After-Free

The vulnerability in the adm1266nvmemreadblackbox function within the drivers/hwmon/pmbus/adm1266.c file of the Linux kernel-based hardware monitoring driver is related to buffer overflow conditions. Exploitation of this vulnerability may allow a remote attacker to compromise the confidentiality,...

SUSE CVE-2026-64135

In the Linux kernel, the following vulnerability has been resolved: hwmon: pmbus/adm1266 widen blackbox-info buffer to I2CSMBUSBLOCKMAX adm1266nvmemreadblackbox declares a 5-byte stack buffer and passes it to i2csmbusreadblockdata to retrieve the 4-byte BLACKBOXINFO response. i2csmbusreadblockdat...

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...

CVE-2026-64086

A flaw was found in the Linux kernel's hwmon hardware monitoring subsystem, specifically in the pmbus/adm1266 driver. The adm1266pmbusblockxfer function attempts to read one byte more than the allocated buffer size during a block transfer read operation. This out-of-bounds write can lead to memor...

CVE-2026-64085

In the Linux kernel, the following vulnerability has been resolved: hwmon: pmbus/adm1266 bounce blackbox records through a protocol-sized buffer adm1266pmbusblockxfer copies the device-supplied block payload into the caller-provided buffer using the device-supplied length: memcpydatar, &msgs1.buf...
