The yamioctl function in drivers/net/hamradio/yam.c in the Linux kernel before 3.12.8 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory by leveraging the CAPNETADMIN capability for an SIOCYAMGCFG ioctl call...

CVE-2014-1444

Technical details beyond the Initial Description are not publicly provided in the connected documents. Monitor for updates from upstream advisories to confirm affected products, versions, and fixes.

CVE-2014-1446

CVE-2014-1446 affects the Linux kernel up to version 3.12.7, where the yam_ioctl handler in drivers/net/hamradio/yam.c fails to initialize a structure member. This can allow a local attacker with CAP_NET_ADMIN to leak kernel memory via an SIOCYAMGCFG ioctl, enabling information disclosure. The ex...

CVE-2013-4343

CVE-2013-4343 is a use-after-free in drivers/net/tun.c of the Linux kernel up to and including 3.11.1. An unprivileged local user with CAP_NET_ADMIN can exploit an invalid tuntap interface name passed to TUNSETIFF to gain privileges. The vulnerability affects the tun/tap subsystem by abusing a us...

CVE-2012-6547

CVE-2012-6547 is the Linux kernel issue where __tun_chr_ioctl in drivers/net/tun.c may leave a structure uninitialized, enabling local users to read kernel stack memory. It is described as affecting Linux kernels prior to 3.6; MiracleLinux advisories list this CVE among others in kernel packages ...

CVE-2012-6547

The tunchrioctl function in drivers/net/tun.c in the Linux kernel before 3.6 does not initialize a certain structure, which allows local users to obtain sensitive information from kernel stack memory via a crafted application...

CVE-2012-2313

The CVE-2012-2313 issue affects the Linux kernel up to version 3.3.7, where rio_ioctl in drivers/net/ethernet/dlink/dl2k.c does not restrict access to the SIOCSMIIREG ioctl. This allows local attackers to write data to an Ethernet adapter via an ioctl call. The vulnerability is rooted in insuffic...

CVE-2011-1581

The bondselectqueue function in drivers/net/bonding/bondmain.c in the Linux kernel before 2.6.39, when a network device with a large number of receive queues is installed but the default txqueues setting is used, does not properly restrict queue indexes, which allows remote attackers to cause a...

CVE-2010-4263

The CVE-2010-4263 issue involves the Intel igb driver (drivers/net/igb/igb_main.c) in the Linux kernel and its handling of VLAN-tagged frames when SR-IOV and promiscuous mode are enabled but no VLANs are registered. In kernels before 2.6.34, processing such frames could trigger a NULL pointer der...

CVE-2010-3298

CVE-2010-3298 affects the Linux kernel. The hso_get_count function in drivers/net/usb/hso.c, in kernel builds before 2.6.36-rc5, does not initialize a certain structure member, which allows local users to read potentially sensitive information from kernel stack memory via the TIOCGICOUNT ioctl. T...

Linux Kernel niu_get_ethtool_tcam_all()函数本地溢出漏洞

Linux Kernel是开放源码操作系统Linux所使用的内核。 drivers/net/niu.c文件中的niugetethtooltcamall函数假设其输出缓冲区已有足够大小，但该缓冲区是受用户控制的，且ETHTOOLGRXCLSRLALL非特权的ethtool命令。这允许本地用户发送特制的ETHTOOLGRXCLSRLALL IOCTL请求导致内核崩溃。 Linux kernel 2.6.x 厂商补丁： Linux ----- 目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载：...

Linux Kernel tun_chr_pool()函数空指针引用漏洞

BUGTRAQ ID: 35724 CVECAN ID: CVE-2009-1894 Linux Kernel是开放源码操作系统Linux所使用的内核。 Linux Kernel的drivers/net/tun.c文件中的tunchrpoll函数存在空指针引用错误： int fd; struct pollfd pfd; fd = open"/dev/net/tun", ORDWR; pfd.fd = fd; pfd.events = POLLIN | POLLOUT; poll&pfd, 1, 0;...

CVE-2008-2812

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...
