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 aixpartition function reads an unvalidated ppcount value, causing it to read beyond the allocated buffe...

CVE-2026-64318

Summary (CVE-2026-64318) : In the Linux kernel, the partitions code for AIX on the PPC/IBM layout could read past the end of the ppe[] array. The function aix_partition() loads a fixed-size pvd and iterates up to the on-disk pp_count, which could exceed the allocated 1016 entries, leading to pote...
