| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2010-01-27 | CVE-2009-4272 | Improper Locking vulnerability in multiple products A certain Red Hat patch for net/ipv4/route.c in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 allows remote attackers to cause a denial of service (deadlock) via crafted packets that force collisions in the IPv4 routing hash table, and trigger a routing "emergency" in which a hash chain is too long. | 7.5 |
| 2009-11-20 | CVE-2009-4004 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Linux Kernel Buffer overflow in the kvm_vcpu_ioctl_x86_setup_mce function in arch/x86/kvm/x86.c in the KVM subsystem in the Linux kernel before 2.6.32-rc7 allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a KVM_X86_SETUP_MCE IOCTL request that specifies a large number of Machine Check Exception (MCE) banks. | 7.8 |
| 2009-11-16 | CVE-2009-3939 | Incorrect Permission Assignment for Critical Resource vulnerability in multiple products The poll_mode_io file for the megaraid_sas driver in the Linux kernel 2.6.31.6 and earlier has world-writable permissions, which allows local users to change the I/O mode of the driver by modifying this file. | 7.1 |
| 2009-11-04 | CVE-2009-3547 | Operation on a Resource after Expiration or Release vulnerability in multiple products Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cause a denial of service (NULL pointer dereference and system crash) or gain privileges by attempting to open an anonymous pipe via a /proc/*/fd/ pathname. | 7.0 |
| 2009-10-22 | CVE-2009-3620 | Use of Uninitialized Resource vulnerability in multiple products The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls. | 7.8 |
| 2009-08-27 | CVE-2009-2698 | NULL Pointer Dereference vulnerability in multiple products The udp_sendmsg function in the UDP implementation in (1) net/ipv4/udp.c and (2) net/ipv6/udp.c in the Linux kernel before 2.6.19 allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) via vectors involving the MSG_MORE flag and a UDP socket. | 7.8 |
| 2009-08-14 | CVE-2009-2768 | NULL Pointer Dereference vulnerability in Linux Kernel The load_flat_shared_library function in fs/binfmt_flat.c in the flat subsystem in the Linux kernel before 2.6.31-rc6 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by executing a shared flat binary, which triggers an access of an "uninitialized cred pointer." | 7.8 |
| 2009-08-14 | CVE-2009-2692 | Use of Uninitialized Resource vulnerability in multiple products The Linux kernel 2.6.0 through 2.6.30.4, and 2.4.4 through 2.4.37.4, does not initialize all function pointers for socket operations in proto_ops structures, which allows local users to trigger a NULL pointer dereference and gain privileges by using mmap to map page zero, placing arbitrary code on this page, and then invoking an unavailable operation, as demonstrated by the sendpage operation (sock_sendpage function) on a PF_PPPOX socket. | 7.8 |
| 2008-07-09 | CVE-2008-2931 | Improper Privilege Management vulnerability in multiple products The do_change_type function in fs/namespace.c in the Linux kernel before 2.6.22 does not verify that the caller has the CAP_SYS_ADMIN capability, which allows local users to gain privileges or cause a denial of service by modifying the properties of a mountpoint. | 7.8 |
| 2008-07-09 | CVE-2008-2812 | NULL Pointer Dereference vulnerability in multiple products The Linux kernel before 2.6.25.10 does not properly perform tty operations, which allows local users to cause a denial of service (system crash) or possibly gain privileges via vectors involving NULL pointer dereference of function pointers in (1) hamradio/6pack.c, (2) hamradio/mkiss.c, (3) irda/irtty-sir.c, (4) ppp_async.c, (5) ppp_synctty.c, (6) slip.c, (7) wan/x25_asy.c, and (8) wireless/strip.c in drivers/net/. | 7.8 |
