CVE-2026-64318

A flaw was found in the Linux kernel's AIX partition handling. A local attacker can provide a specially crafted AIX/IBM partition table on a block device. When the kernel scans this device, the aix_partition() function reads an unvalidated pp_count value, causing it to read beyond the allocated buffer. This out-of-bounds read can lead to information disclosure, potentially revealing sensitive kernel memory, and may also result in a denial of service.
