CVE-2022-50184

The CVE-2022-50184 issue in the Linux kernel concerns a refcount leak in the Meson HDMI encoder path. Specifically, in drm/meson: encoder_hdmi_init, of_graph_get_remote_node() returns a remote device node pointer with an incremented refcount, and a missing of_node_put() could lead to a leak. The ...

CVE-2022-50185

In CVE-2022-50185, the Linux kernel drm/radeon path ni_set_mc_special_registers() is vulnerable to a potential buffer overflow. The last case label could write mc_reg_address[j] and mc_data[j] when j equals SMC_NISLANDS_MC_REGISTER_ARRAY_SIZE due to missing bounds checks after the last j++. The f...
