Description:
Two vulnerabilities have been reported in the Linux Kernel, which can be exploited by malicious, local users to disclose potentially sensitive information, and to cause a DoS (Denial of Service).
1) The "dm-crypt" driver fails to clear memory before freeing it. This can be exploited by local users to obtain sensitive information (e.g. cryptographic keys).
The vulnerability has been reported in version 2.6.15.1. Other versions may also be affected.
2) An error in the "mq_open" system call can cause the "mqueue_mnt->mnt_count" counter to be decremented twice when the "dentry_open" function call fails. This can potentially be exploited by malicious users to cause a kernel panic.
