CVE-2026-64135

CVE-2026-64135 affects the Linux kernel hwmon driver for the ADM1266 (pmbus) by leaking a 5-byte stack buffer in adm1266_nvmem_read_blackbox(). The code passes a 5-byte local buffer to i2c_smbus_read_block_data(), which can copy data.block[0] bytes from the SMBus response without honoring the cal...

CVE-2026-64087

In the Linux kernel hwmon subsystem (pmbus/adm1266), adm1266_nvmem_read_blackbox() could loop using a record_count from BLACKBOX_INFO, risking a read past data->dev_mem when a device reports >32 records (due to firmware, bus issues, or 0xff). The fix caps the record_count at ADM1266_BLACKBO...

CVE-2026-64085

The CVE describes a Linux kernel hwmon issue (adm1266) where adm1266_pmbus_block_xfer() copies a device-supplied block payload into a caller buffer using msgs[1].buf[0] as length. The helper may write more than the protected ADM1266_BLACKBOX_SIZE (64 bytes), while the caller advances read_buff in...
