UBUNTU-CVE-2026-43328

In the Linux kernel, the following vulnerability has been resolved: cpufreq: governor: fix double free in cpufreqdbsgovernorinit error path When kobjectinitandadd fails, cpufreqdbsgovernorinit calls kobjectput&dbsdata-attrset.kobj. The kobject release callback cpufreqdbsdatarelease calls...

CVE-2026-43328

Root cause: in the Linux kernel cpufreq governor, the error path in cpufreq_dbs_governor_init() could trigger a double free when kobject_init_and_add() fails. The kobject release path previously attempted cleanup via gov->exit(dbs_data) and kfree(dbs_data) twice. The fix keeps a direct kfree(d...
