Bottlerocket: kernel-5.10, kernel-5.15: security update to 2.7.0
medium Tenable Cloud Security Plugin ID 428013
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: soc: qcom: cmd-db: Map shared memory
as WC, not WB Linux does not write into cmd-db region. This region of memory is write protected by XPU.
XPU may sometime falsely detect clean cache eviction as "write" into the write protected region leading to
secure interrupt which causes an endless loop somewhere in Trust Zone. The only reason it is working right
now is because Qualcomm Hypervisor maps the same region as Non-Cacheable memory in Stage 2 translation
tables. The issue manifests if we want to use another hypervisor (like Xen or KVM), which does not know
anything about those specific mappings. Changing the mapping of cmd-db memory from MEMREMAP_WB to
MEMREMAP_WT/WC removes dependency on correct mappings in Stage 2 tables. This patch fixes the issue by
updating the mapping to MEMREMAP_WC. I tested this on SA8155P with Xen. (CVE-2024-46689)
