From: Dan Carpenter Date: Tue, 1 Jul 2025 22:30:01 +0000 (-0500) Subject: cpufreq: armada-8k: Fix off by one in armada_8k_cpufreq_free_table() X-Git-Tag: v5.10.241~172 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=eb2df34b54ea2c3de4500129f6db4aa6a0979afd;p=thirdparty%2Fkernel%2Fstable.git cpufreq: armada-8k: Fix off by one in armada_8k_cpufreq_free_table() commit 4a26df233266a628157d7f0285451d8655defdfc upstream. The freq_tables[] array has num_possible_cpus() elements so, to avoid an out of bounds access, this loop should be capped at "< nb_cpus" instead of "<= nb_cpus". The freq_tables[] array is allocated in armada_8k_cpufreq_init().
