To address the above issue, simplify the kvm_pmu_clear_snapshot_area() to not zero-out PMU snapshot area from kvm_pmu_clear_snapshot_area() because the guest is anyway being tore down. The kvm_pmu_clear_snapshot_area() is also called when guest changes PMU snapshot area of a VCPU but even in this case the previous PMU snaphsot area must not be zeroed-out because the guest might have reclaimed the pervious PMU snapshot area for some other purpose. | 5.5 |
| 2024-10-21 | CVE-2024-47720 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add null check for set_output_gamma in dcn30_set_output_transfer_func This commit adds a null check for the set_output_gamma function pointer in the dcn30_set_output_transfer_func function. | 5.5 |
| 2024-10-17 | CVE-2024-47459 | NULL Pointer Dereference vulnerability in Adobe Substance 3D Sampler 4.2.1 Substance3D - Sampler versions 4.5 and earlier are affected by a NULL Pointer Dereference vulnerability that could lead to an application denial-of-service (DoS) condition. | 5.5 |
| 2024-10-11 | CVE-2024-47496 | A NULL Pointer Dereference vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS allows a local, low-privileged attacker to cause a Denial-of-Service (DoS). When a specific command is executed, the pfe crashes. This will cause traffic forwarding to be interrupted until the system self-recovers. | 5.5 |
| 2024-10-11 | CVE-2024-47501 | A NULL Pointer Dereference vulnerability in the packet forwarding engine (pfe) of Juniper Networks Junos OS on MX304, MX with MPC10/11/LC9600, and EX9200 with EX9200-15C allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS). In a VPLS or Junos Fusion scenario, the execution of specific show commands will cause all FPCs hosting VPLS sessions or connecting to satellites to crash and restart. This issue affects Junos on MX304, MX with MPC10/11/LC9600 and EX9200 with EX9200-15C: * All version before 21.2R3-S1, * 21.3 versions before 21.3R3, * 21.4 versions before 21.4R2. | 5.5 |
