Description:
Two vulnerabilities have been reported in the Linux Kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service).
1) The it87 and via686a hardware monitoring drivers create the sysfs file "alarms" with insecure permissions granting write access to the file. This can be exploited to exhaust all available CPU resources by writing to the file.
2) An error in the "key_user_lookup()" function in "security/keys/key.c" can be exploited to crash the kernel.
