"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nata: ahci: fail probe if BAR too small for claimed ports\n\nWhen an AHCI controller is disabled in BIOS, its HOST_CAP register may\ncontain a bogus value, e.g. 0xFFFFFFFF.\n\nSince CAP.NP (Number of Ports) is a zeroes based 5-bit register field,\na value of 0x1f means 32 ports. If CAP.NP claims more ports than can\nphysically fit within the mapped BAR region, accessing port registers\nbeyond the BAR boundary causes a kernel panic.\n\nAdd validation in ahci_init_one() to check that the BAR size is\nsufficient for the number of ports claimed in CAP.NP. The check\ncalculates the required MMIO size as:\n\n required_size = 0x100 (global registers) + max_ports * 0x80\n\nIf required_size exceeds the actual BAR size, the probe fails with\n-ENODEV, preventing the panic and providing a clear error message.\n\n[cassel: commit log]"
