#VU94462 Improper error handling in Linux kernel - CVE-2024-41008

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper error handling within the kfd_smi_event_update_thermal_throttling() function in drivers/gpu/drm/amd/amdkfd/kfd_smi_events.c, within the sdma_v4_4_2_print_iv_entry() function in drivers/gpu/drm/amd/amdgpu/sdma_v4_4_2.c, within the sdma_v4_0_print_iv_entry() function in drivers/gpu/drm/amd/amdgpu/sdma_v4_0.c, within the gmc_v9_0_process_interrupt() function in drivers/gpu/drm/amd/amdgpu/gmc_v9_0.c, within the gmc_v8_0_process_interrupt() function in drivers/gpu/drm/amd/amdgpu/gmc_v8_0.c, within the gmc_v11_0_process_interrupt() function in drivers/gpu/drm/amd/amdgpu/gmc_v11_0.c, within the gmc_v10_0_process_interrupt() function in drivers/gpu/drm/amd/amdgpu/gmc_v10_0.c, within the amdgpu_vm_ptes_update() function in drivers/gpu/drm/amd/amdgpu/amdgpu_vm_pt.c, within the amdgpu_vm_validate(), amdgpu_vm_wait_idle(), amdgpu_vm_init(), amdgpu_vm_fini() and amdgpu_vm_ioctl() functions in drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c, within the amdgpu_coredump() function in drivers/gpu/drm/amd/amdgpu/amdgpu_reset.c, within the amdgpu_job_timedout() function in drivers/gpu/drm/amd/amdgpu/amdgpu_job.c, within the amdgpu_gem_object_open() function in drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c, within the amdgpu_debugfs_vm_info_show() function in drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c. A local user can perform a denial of service (DoS) attack.
