#	CVE ID	CWE ID	# of Exploits	Vulnerability Type(s)	Publish Date	Update Date	Score	Gained Access Level	Access	Complexity	Authentication	Conf.	Integ.	Avail.
1	CVE-2012-4444			Bypass	2012-12-21	2013-02-07	5.0	None	Remote	Low	Not required	None	Partial	None
The ip6_frag_queue function in net/ipv6/reassembly.c in the Linux kernel before 2.6.36 allows remote attackers to bypass intended network restrictions via overlapping IPv6 fragments.
2	CVE-2012-2123	264		Bypass	2012-05-17	2013-02-14	7.2	None	Local	Low	Not required	Complete	Complete	Complete
The cap_bprm_set_creds function in security/commoncap.c in the Linux kernel before 3.3.3 does not properly handle the use of file system capabilities (aka fcaps) for implementing a privileged executable file, which allows local users to bypass intended personality restrictions via a crafted application, as demonstrated by an attack that uses a parent process to disable ASLR.
3	CVE-2011-4127	264		Bypass	2012-07-03	2012-12-18	4.6	None	Local	Low	Not required	Partial	Partial	Partial
The Linux kernel before 3.2.2 does not properly restrict SG_IO ioctl calls, which allows local users to bypass intended restrictions on disk read and write operations by sending a SCSI command to (1) a partition block device or (2) an LVM volume.
4	CVE-2011-4080	264		Bypass	2012-05-24	2012-05-29	4.0	None	Local	High	Not required	Complete	None	None
The sysrq_sysctl_handler function in kernel/sysctl.c in the Linux kernel before 2.6.39 does not require the CAP_SYS_ADMIN capability to modify the dmesg_restrict value, which allows local users to bypass intended access restrictions and read the kernel ring buffer by leveraging root privileges, as demonstrated by a root user in a Linux Containers (aka LXC) environment.
5	CVE-2011-1833	264		Bypass	2012-10-03	2012-10-03	3.3	None	Local	Medium	Not required	Partial	Partial	None
Race condition in the ecryptfs_mount function in fs/ecryptfs/main.c in the eCryptfs subsystem in the Linux kernel before 3.1 allows local users to bypass intended file permissions via a mount.ecryptfs_private mount with a mismatched uid.
6	CVE-2011-0006	264		Bypass	2012-06-21	2012-06-26	1.9	None	Local	Medium	Not required	None	Partial	None
The ima_lsm_rule_init function in security/integrity/ima/ima_policy.c in the Linux kernel before 2.6.37, when the Linux Security Modules (LSM) framework is disabled, allows local users to bypass Integrity Measurement Architecture (IMA) rules in opportunistic circumstances by leveraging an administrator's addition of an IMA rule for LSM.
