Updated

An information leak was discovered in the Linux kernel when inotify is used to monitor the /dev/ptmx device. A local user could exploit this flaw to discover keystroke timing and potentially discover sensitive information like password length. (CVE-2013-0160) A flaw was discovered in the Linux kernel's perf events subsystem for Intel Sandy Bridge and Ivy Bridge processors. A local user could exploit this flaw to cause a denial of service (system crash). (CVE-2013-2146) An information leak was discovered in the Linux kernel's crypto API. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3076) An information leak was discovered in the Linux kernel's rcvmsg path for ATM (Asynchronous Transfer Mode). A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3222) An information leak was discovered in the Linux kernel's recvmsg path for ax25 address family. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3223) An information leak was discovered in the Linux kernel's recvmsg path for the bluetooth address family. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3224) An information leak was discovered in the Linux kernel's bluetooth rfcomm protocol support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3225) An information leak was discovered in the Linux kernel's CAIF protocol implementation. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3227) An information leak was discovered in the Linux kernel's IRDA (infrared) support subsystem. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3228) An information leak was discovered in the Linux kernel's s390 - z/VM support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3229) An information leak was discovered in the Linux kernel's llc (Logical Link Layer 2) support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3231) An information leak was discovered in the Linux kernel's receive message handling for the netrom address family. A local user could exploit this flaw to obtain sensitive information from the kernel's stack memory. (CVE-2013-3232) An information leak was discovered in the Linux kernel's Rose X.25 protocol layer. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3234) An information leak was discovered in the Linux kernel's TIPC (Transparent Inter Process Communication) protocol implementation. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3235)
