CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-46694 – drm/amd/display: avoid using null object of framebuffer
https://notcve.org/view.php?id=CVE-2024-46694
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: avoid using null object of framebuffer Instead of using state->fb->obj[0] directly, get object from framebuffer by calling drm_gem_fb_get_obj() and return error code when object is null to avoid using null object of framebuffer.

CVSS: -EPSS: 0%CPEs: 7EXPL: 0CVE-2024-46689 – soc: qcom: cmd-db: Map shared memory as WC, not WB
https://notcve.org/view.php?id=CVE-2024-46689
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. • https://git.kernel.org/stable/c/312416d9171a1460b7ed8d182b5b540c910ce80d https://git.kernel.org/stable/c/0ee9594c974368a17e85a431e9fe1c14fb65c278 https://git.kernel.org/stable/c/f5a5a5a0e95f36e2792d48e6e4b64e665eb01374 https://git.kernel.org/stable/c/eaff392c1e34fb77cc61505a31b0191e5e46e271 https://git.kernel.org/stable/c/d9d48d70e922b272875cda60d2ada89291c840cf https://git.kernel.org/stable/c/ef80520be0ff78ae5ed44cb6eee1525e65bebe70 https://git.kernel.org/stable/c/62c2d63605ca25b5db78a347ed303c0a0a77d5b4 https://git.kernel.org/stable/c/f9bb896eab221618927ae6a2f1d566567 •

In the Linux kernel, the following vulnerability has been resolved: pktgen: use cpus_read_lock() in pg_net_init() I have seen the WARN_ON(smp_processor_id() != cpu) firing in pktgen_thread_worker() during tests. We must use cpus_read_lock()/cpus_read_unlock() around the for_each_online_cpu(cpu) loop. While we are at it use WARN_ON_ONCE() to avoid a possible syslog flood. • https://git.kernel.org/stable/c/1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 https://git.kernel.org/stable/c/5f5f7366dda8ae870e8305d6e7b3c0c2686cd2cf https://git.kernel.org/stable/c/979b581e4c69257acab1af415ddad6b2d78a2fa5 •
