CVE-2024-56785

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.74

Description A vulnerability in the Linux kernel has been resolved, specifically related to the MIPS Loongson64 architecture. The issue involved fixing PCIe port nodes for ls7a and resolving dtc warnings. A runtime warning was introduced due to deprecated #address-cells/#size-cells handling. The fix is similar to a previous commit that resolved the issue for ls2k.

Recommendations Update to Linux kernel version 6.6.74 or later to resolve the issue. As a temporary workaround, consider disabling the vulnerable PCIe port nodes for ls7a until a patch is available. Restrict access to the affected PCI bridge to minimize the risk of exploitation.
