UBUNTU-CVE-2021-47387

In the Linux kernel, the following vulnerability has been resolved: cpufreq: schedutil: Use kobject release method to free sugovtunables The struct sugovtunables is protected by the kobject, so we can't free it directly. Otherwise we would get a call trace like this: ODEBUG: free active active...

In the Linux kernel, the following vulnerability has been resolved: cpufreq: schedutil: Use kobject release method to free sugovtunables The struct sugovtunables is protected by the kobject, so we can't free it directly. Otherwise we would get a call trace like this: ODEBUG: free active active...

CVE-2021-47387

CVE-2021-47387 is a Linux kernel vulnerability in the cpufreq: schedutil governor related to freeing sugov_tunables. The original sugov_tunables_free() was split: sugov_clear_global_tunables() clears the global_tunables, and a new sugov_tunables_free() is used as kobj_type::release to safely free...

kernel: cpufreq: governor: Use kobject release() method to free dbs_data

A vulnerability was found in the Linux kernel's cpufreq subsystem. The dbsdata struct, which embeds a kobject, improperly attempts to free the struct using kfree rather than through the proper release method. This issue can lead to a use-after-free scenario, resulting in system instability, memor...
