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...

CVE-2021-47387: Release of Invalid Pointer or Reference

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...

Move the setting name validation...

The vulnerabilities of the functions create_dir(), __kobject_del(), kobject_cleanup(), and kobj_child_ns_ops() in the b/kobject.c library of the Linux operating system’s kernel allow a attacker to cause a service failure.

The vulnerabilities of the functions createdir, kobjectdel, kobjectcleanup, and kobjchildnsops in the b/kobject.c library of the Linux operating system are related to pointer arithmetic errors. Exploiting these vulnerabilities can allow a remote attacker to cause service interruptions...
