CVE-2026-45994

A flaw was found in the Linux kernel's ibmasm module. This vulnerability, an out-of-bounds read in the `command_file_write` function, allows an attacker to cause the system to read beyond the intended memory boundaries. By manipulating the allocation size and header fields, an attacker can trigger this flaw, leading to the disclosure of sensitive kernel heap memory to the service processor. This could result in unauthorized access to confidential system information.
