Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.15.0-25-generic #25-Ubuntu

Description An array-index-out-of-bounds issue was identified in the Linux kernel's AHCI driver. The sata pmp init links() function initializes link->pmp up to SATA PMP MAX PORTS, while the em priv array is declared with a size of 8 elements. This discrepancy can lead to a UBSAN error when accessing the array out of bounds. The issue arises from a mismatch between the maximum number of Enclosure Management ports and the allocated array size.

Recommendations Update to Linux kernel version 5.15.0-25-generic #25-Ubuntu or later.
