CVE-2026-46247

/// Technical description

In the Linux kernel, the following vulnerability has been resolved:

clk: qcom: gfx3d: add parent to parent request map

After commit d228ece36345 ("clk: divider: remove round_rate() in favor

of determine_rate()") determining GFX3D clock rate crashes, because the

passed parent map doesn't provide the expected best_parent_hw clock

(with the roundd_rate path before the offending commit the

best_parent_hw was ignored).

Set the field in parent_req in addition to setting it in the req,

fixing the crash.
