Linux kernel 资源管理错误漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. Linux kernel suffers from a resource management error vulnerability that stems from a flaw in the way the unixstreamrecvmsg function frees memory resources when a signal hangs...

CVE-2019-3837

It was found that the netdma code in tcprecvmsg in the RHEL6 kernel is thread-unsafe. So an unprivileged multi-threaded userspace application calling recvmsg for the same network socket in parallel executed on ioatdma-enabled hardware with netdma enabled can leak the memory, crash the host leadin...

Name of the Vulnerable Software and Affected Versions: Linux kernel version 2.6.32 Description: The issue is related to the net dma code in the tcp recvmsg function, which is thread-unsafe. This can be exploited by an unprivileged multi-threaded userspace application calling recvmsg for the same...

DEBIAN-CVE-2017-14106

The tcpdisconnect function in net/ipv4/tcp.c in the Linux kernel before 4.12 allows local users to cause a denial of service tcpselectwindow divide-by-zero error and system crash by triggering a disconnect within a certain tcprecvmsg code path...

The vulnerability of the Linux operating system allows a malicious individual to gain access to confidential information from the kernel’s memory.

A local user can access the kernel memory due to information leakage during the execution of system calls recvmmsg and recvmsg...

CVE-2015-8019

The skbcopyandcsumdatagramiovec function in net/core/datagram.c in the Linux kernel 3.14.54 and 3.18.22 does not accept a length argument, which allows local users to cause a denial of service memory corruption or possibly have unspecified other impact via a write system call followed by a recvms...

Kernel: net: information leak in recvmsg handler msg_name & msg_namelen logic

The mISDNsockrecvmsg function in drivers/isdn/mISDN/socket.c in the Linux kernel before 3.12.4 does not ensure that a certain length value is consistent with the size of an associated data structure, which allows local users to obtain sensitive information from kernel memory via a 1 recvfrom, 2...

Kernel: net: leakage of uninitialized memory to user-space via recv syscalls

The Linux kernel before 3.12.4 updates certain length values before ensuring that associated data structures have been initialized, which allows local users to obtain sensitive information from kernel stack memory via a 1 recvfrom, 2 recvmmsg, or 3 recvmsg system call, related to net/ipv4/ping.c,...
