Memory leak via unreleased PLL rate table
Published Dec 24, 2025 · Updated Dec 24, 2025
A memory leak in the Visconti PLL clock driver in Linux 5.17 through 6.0.15 and 6.1 through 6.1.1 allows attackers to consume kernel memory. The visconti_register_pll function duplicates pll->rate_table with kmemdup but fails to release that allocation when clk_hw_register returns an error. The leak requires PLL registration to reach that failure path; published material identifies neither an attacker-controlled trigger nor a resulting crash or hang.
