CVE-2011-1172: net/ipv6/netfilter/ip6_tables.c in the IPv6 implementation in the Linux kernel did not place the expected 0 character at the end of string data in the values of certain structure members, which allowed local users to obtain potentially sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability to issue a crafted request, and then reading the argument to the resulting modprobe process.

CVE-2011-2525: The qdisc_notify function in net/sched/sch_api.c in the Linux kernel did not prevent tc_fill_qdisc function calls referencing builtin (aka CQ_F_BUILTIN) Qdisc structures, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via a crafted call.

CVE-2011-2699: The IPv6 implementation in the Linux kernel did not generate Fragment Identification values separately for each destination, which made it easier for remote attackers to cause a denial of service (disrupted networking) by predicting these values and sending crafted packets.

CVE-2011-1171: net/ipv4/netfilter/ip_tables.c in the IPv4 implementation in the Linux kernel did not place the expected 0 character at the end of string data in the values of certain structure members, which allowed local users to obtain potentially sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability to issue a crafted request, and then reading the argument to the resulting modprobe process.

CVE-2011-1170: net/ipv4/netfilter/arp_tables.c in the IPv4 implementation in the Linux kernel did not place the expected 0 character at the end of string data in the values of certain structure members, which allowed local users to obtain potentially sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability to issue a crafted request, and then reading the argument to the resulting modprobe process.

CVE-2011-3209: The div_long_long_rem implementation in include/asm-x86/div64.h in the Linux kernel on the x86 platform allowed local users to cause a denial of service (Divide Error Fault and panic) via a clock_gettime system call.

CVE-2011-2213: The inet_diag_bc_audit function in net/ipv4/inet_diag.c in the Linux kernel did not properly audit INET_DIAG bytecode, which allowed local users to cause a denial of service (kernel infinite loop) via crafted INET_DIAG_REQ_BYTECODE instructions in a netlink message, as demonstrated by an INET_DIAG_BC_JMP instruction with a zero yes value, a different vulnerability than CVE-2010-3880.

CVE-2011-2534: Buffer overflow in the clusterip_proc_write function in net/ipv4/netfilter/ipt_CLUSTERIP.c in the Linux kernel might have allowed local users to cause a denial of service or have unspecified other impact via a crafted write operation, related to string data that lacks a terminating 0 character.

CVE-2011-2699: The IPv6 implementation in the Linux kernel did not generate Fragment Identification values separately for each destination, which made it easier for remote attackers to cause a denial of service (disrupted networking) by predicting these values and sending crafted packets.

CVE-2011-2203: The hfs_find_init function in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and Oops) by mounting an HFS file system with a malformed MDB extent record.

CVE-2009-4067: A USB string descriptor overflow in the auerwald USB driver was fixed, which could be used by physically proximate attackers to cause a kernel crash.

CVE-2011-3363: The setup_cifs_sb function in fs/cifs/connect.c in the Linux kernel did not properly handle DFS referrals, which allowed remote CIFS servers to cause a denial of service (system crash) by placing a referral at the root of a share.

CVE-2011-2484: The add_del_listener function in kernel/taskstats.c in the Linux kernel did not prevent multiple registrations of exit handlers, which allowed local users to cause a denial of service (memory and CPU consumption), and bypass the OOM Killer, via a crafted application.

CVE-2011-4132: The cleanup_journal_tail function in the Journaling Block Device (JBD) functionality in the Linux kernel allowed local users to cause a denial of service (assertion error and kernel oops) via an ext3 or ext4 image with an 'invalid log first block value.'

CVE-2010-4249: The wait_for_unix_gc function in net/unix/garbage.c in the Linux kernel before 2.6.37-rc3-next-20101125 does not properly select times for garbage collection of inflight sockets, which allows local users to cause a denial of service (system hang) via crafted use of the socketpair and sendmsg system calls for SOCK_SEQPACKET sockets.
