CVE-2011-2521

Linux kernel Performance Events vulnerability CVE-2011-2521: the x86_assign_hw_event path in arch/x86/kernel/cpu/perf_event.c miscalculates counter values, allowing a local user to trigger a denial of service (kernel panic) via the perf tool. Affected: Linux kernel before 2.6.39. Root cause: inco...

CVE-2011-2518

The CVE-2011-2518 entry concerns the Linux kernel code path security/tomoyo/mount.c: tomoyo_mount_acl calls kern_path with arguments from the mount system call. This allows local users to trigger a denial of service (OOPS) or possibly other impact via a NULL device name in kernels before 2.6.39.2...

CVE-2011-2707

The CVE-2011-2707 entry affects the Linux kernel's arch/xtensa/kernel/ptrace.c, where the ptrace_setxregs() function does not validate user-space pointers. This allows a local user to read kernel memory via a crafted PTRACE_SETXTREGS request, as described for Linux kernel versions before 3.1. Pub...

CVE-2012-2127

CVE-2012-2127 affects the Linux kernel prior to 3.2, where fs/proc/root.c in procfs does not properly interact with CLONE_NEWPID clone system calls. This can enable a remote attacker to trigger a denial of service via a reference leak and growing memory usage by opening many connections to a PID-...

CVE-2011-2209

The CVE-2011-2209 issue affects the Linux kernel on the Alpha architecture, where an integer signedness error in osf_sysinfo (arch/alpha/kernel/osf_sys.c) could allow local users to obtain sensitive information from kernel memory via a crafted call. Vulnerable when using kernel versions before 2....

CVE-2011-4325

CVE-2011-4325 – Linux kernel NFS vulnerability : The NFS implementation in the Linux kernel up to 2.6.31-rc6 can dereference uninitialized data, enabling a local denial-of-service via NULL pointer dereference and an O_DIRECT oops (e.g., demonstrated with diotest4 from LTP). Affected component: ke...

CVE-2011-2493

The CVE-2011-2493 entry affects the Linux kernel, specifically the ext4_fill_super function in fs/ext4/super.c, with vulnerability present in versions prior to 2.6.39. The issue arises from improper initialization of an error-report data structure, enabling local users to cause a denial of servic...

CVE-2011-2211

CVE-2011-2211 concerns the Linux kernel on the Alpha architecture. The vulnerability lies in the osf_wait4 function (arch/alpha/kernel/osf_sys.c), where an incorrect pointer is used in versions prior to 2.6.39.4. This can allow local users to gain elevated privileges by writing a specific integer...

CVE-2011-2208

The CVE-2011-2208 vulnerability affects the Linux kernel on the Alpha platform, caused by an integer signedness error in osf_getdomainname in arch/alpha/kernel/osf_sys.c. It allows local users to access sensitive kernel memory. Impact is limited to local exploitation with partial confidentiality ...

CVE-2011-4112

CVE-2011-4112 affects the Linux kernel net subsystem prior to 3.1. The issue arises from improper restriction of the IFF_TX_SKB_SHARING flag, enabling local users with CAP_NET_ADMIN to access /proc/net/pktgen/pgctrl and, using the pktgen package with a bridge device for a VLAN interface, trigger ...

CVE-2012-4467

The vulnerability CVE-2012-4467 affects the Linux kernel (pre-3.5.4). The affected code paths are the do_siocgstamp and do_siocgstampns functions in net/socket.c, which use an incorrect argument order, enabling local users to either read sensitive kernel memory or trigger a denial of service (sys...

CVE-2011-2906

The issue is an integer signedness error in the Linux kernel's pmcraid_ioctl_passthrough under drivers/scsi/pmcraid.c, affecting pre-3.1 kernels. It may allow local attackers to cause denial of service via a negative size value in an ioctl call, typically in environments with a privileged program...

CVE-2011-2210

The CVE-2011-2210 issue affects the Linux kernel on the Alpha platform, where osf_getsysinfo in arch/alpha/kernel/osf_sys.c does not properly bound the data size for GSI_GET_HWRPB, enabling local users to read kernel memory. Public sources confirm the root cause is improper data size restriction ...

CVE-2012-0058

The CVE-2012-0058 issue affects the Linux kernel up to version 3.2.2, in the kiocb_batch_free function of fs/aio.c, caused by incorrect iocb management. It allows local attackers to cause a denial of service (OOPS). Impact is confined to local execution, with availability as the primary effect de...
