DEBIAN-CVE-2024-26938

In the Linux kernel, the following vulnerability has been resolved: drm/i915/bios: Tolerate devdata==NULL in intelbiosencodersupportsdpdualmode If we have no VBT, or the VBT didn't declare the encoder in question, we won't have the 'devdata' for the encoder. Instead of oopsing just bail early. We...

CVE-2024-26938

CVE-2024-26938 is a Linux kernel vulnerability in the drm/i915/bios path. The issue occurs when int​el_bios_encoder_supports_dp_dual_mode() encounters a NULL devdata for a DP encoder (e.g., if there is no VBT or the VBT does not declare the encoder). The kernel previously could oops or mis-handle...
