Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: ACPI: PCI: Clear driver_data on all
 paths that free the acpi_pci_root acpi_pci_root_add() assigns the freshly allocated root to
 device->driver_data before dmar_device_add() and pci_acpi_scan_root(). Both failure paths reach the end:
 label where root is kfree()'d, but only the pci_acpi_scan_root() path clears driver_data first. When
 dmar_device_add() fails during a hot-add, root is freed while device->driver_data still points at it. The
 ACPI core does not clear driver_data on attach failure, so a later acpi_pci_find_root() call may
 dereference this dangling pointer. acpi_pci_root_remove() has the same problem: it frees root without
 clearing device->driver_data, leaving a dangling pointer behind after the root bridge is removed. Move the
 NULL assignment to the shared end: label so every error path in acpi_pci_root_add() clears driver_data
 before freeing root, and clear it in acpi_pci_root_remove() as well, so the object is never left reachable
 through driver_data after being freed. (CVE-2026-92521)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
