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...
