CVE-2026-80704

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A NULL pointer dereference occurs in the Linux kernel within the drm/amd/display component. The function get ss info from atombios() attempts to use calc pll cs->ctx->logger for logging via DC LOG SYNC(), but calc pll cs->ctx is not initialized until the subsequent call to calc pll max vco construct(). Similar issues exist in the dce112 get pix clk dividers() and dcn3 get pix clk dividers() functions. The issue is resolved by redefining DC LOGGER to use clk src->base.ctx->logger, which is initialized earlier in dce110 clk src construct() and dce112 clk src construct().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
