#VU100159 Memory leak in Linux kernel - CVE-2024-50214

Description

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

The vulnerability exists due to memory leak within the drm_test_drm_hdmi_compute_mode_clock_rgb(), drm_test_drm_hdmi_compute_mode_clock_rgb_10bpc(), drm_test_drm_hdmi_compute_mode_clock_rgb_10bpc_vic_1(), drm_test_drm_hdmi_compute_mode_clock_rgb_12bpc(), drm_test_drm_hdmi_compute_mode_clock_rgb_12bpc_vic_1(), drm_test_drm_hdmi_compute_mode_clock_rgb_double(), drm_test_connector_hdmi_compute_mode_clock_yuv420_valid(), drm_test_connector_hdmi_compute_mode_clock_yuv420_10_bpc(), drm_test_connector_hdmi_compute_mode_clock_yuv420_12_bpc(), drm_test_connector_hdmi_compute_mode_clock_yuv422_8_bpc(), drm_test_connector_hdmi_compute_mode_clock_yuv422_10_bpc() and drm_test_connector_hdmi_compute_mode_clock_yuv422_12_bpc() functions in drivers/gpu/drm/tests/drm_connector_test.c. A local user can perform a denial of service (DoS) attack.
