The x86 emulator in KVM 83 does not use the Current Privilege Level (CPL) and I/O Privilege Level (IOPL) in determining the memory access available to CPL3 code, which allows guest OS users to cause a denial of service (guest OS crash) or gain privil...

A certain Red Hat configuration step for the qla2xxx driver in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5, when N_Port ID Virtualization (NPIV) hardware is used, sets world-writable permissions for the (1) vport_create and (2) vport...

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...

The print_fatal_signal function in kernel/signal.c in the Linux kernel before 2.6.32.4 on the i386 platform, when print-fatal-signals is enabled, allows local users to discover the contents of arbitrary memory locations by jumping to an address and t...

The ipv6_hop_jumbo function in net/ipv6/exthdrs.c in the Linux kernel before 2.6.32.4, when network namespaces are enabled, allows remote attackers to cause a denial of service (NULL pointer dereference) via an invalid IPv6 jumbogram, a related issue...

net/bridge/netfilter/ebtables.c in the ebtables module in the netfilter framework in the Linux kernel before 2.6.33-rc4 does not require the CAP_NET_ADMIN capability for setting or modifying rules, which allows local users to bypass intended access r...

Use-after-free vulnerability in the fasync_helper function in fs/fcntl.c in the Linux kernel before 2.6.33-rc4-git1 allows local users to gain privileges via vectors that include enabling O_ASYNC (aka FASYNC or FIOASYNC) on a locked file, and then cl...

drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel 2.6.32.3 and earlier handles Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete frame, which allows remote attackers to bypas...

drivers/net/r8169.c in the r8169 driver in the Linux kernel 2.6.32.3 and earlier does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to (1) cause a denial of service (temporary network outage) via...

drivers/net/e1000e/netdev.c in the e1000e driver in the Linux kernel 2.6.32.3 and earlier does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to have an unspecified impact via crafted packets, a r...
