CVE-2026-64087

A flaw was found in the Linux kernel's pmbus/adm1266 driver. A malformed response from a hardware monitoring device could cause the driver to read beyond the allocated memory buffer. This out-of-bounds read can lead to system instability or denial of service...

CVE-2026-64085

A flaw was found in the Linux kernel's pmbus/adm1266 driver, which is responsible for hardware monitoring. This vulnerability occurs because the driver does not properly handle data sizes when reading blackbox records from a device. A malicious or malformed device could send more data than...

CVE-2026-64084

A flaw was found in the Linux kernel's hardware monitoring hwmon subsystem, specifically within the pmbus/adm1266 driver. This vulnerability involves an out-of-bounds memory access, where the system attempts to read or write data beyond the allocated memory region. A local attacker could exploit...

CVE-2026-64085

CVE-2026-64085 is a buffer overflow in the Linux kernel's hwmon (pmbus/adm1266) driver. The helper adm1266_pmbus_block_xfer() trusts the device-supplied length and can write up to 255 bytes , but adm1266_nvmem_read_blackbox() advances in 64-byte strides within a 2048-byte dev_mem buffer. On the t...

CVE-2026-64086

The CVE-2026-64086 issue affects the Linux kernel PMBUS adm1266 hwmon path. A read transaction for the pmbus_block_xfer path set .len to ADM1266_PMBUS_BLOCK_MAX + 2 while read_buf was declared as ADM1266_PMBUS_BLOCK_MAX + 1. For max-length block responses, this allowed writing 257 bytes into a 25...
