Echo: linux: security update to 6.8.9-1

medium Tenable Self-Hosted Container Security Plugin ID 462141

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: iommu/vt-d: Use device rbtree in iopf
 reporting path The existing I/O page fault handler currently locates the PCI device by calling
 pci_get_domain_bus_and_slot(). This function searches the list of all PCI devices until the desired device
 is found. To improve lookup efficiency, replace it with device_rbtree_find() to search the device within
 the probed device rbtree. The I/O page fault is initiated by the device, which does not have any
 synchronization mechanism with the software to ensure that the device stays in the probed device tree.
 Theoretically, a device could be released by the IOMMU subsystem after device_rbtree_find() and before
 iopf_get_dev_fault_param(), which would cause a use-after-free problem. Add a mutex to synchronize the I/O
 page fault reporting path and the IOMMU release device path. This lock doesn't introduce any performance
 overhead, as the conflict between I/O page fault reporting and device releasing is very rare.
 (CVE-2024-35843)

Solution

Update the linux library and its related packages to version 6.8.9-1 or later.
