kernel: vhost-net: stack overflow in get_raw_socket while checking sk_family field

A stack buffer overflow issue was found in the getrawsocket routine of the Host kernel accelerator for virtio net vhost-net driver. It could occur while doing an ictolVHOSTNETSETBACKEND call, and retrieving socket name in a kernel stack variable via getrawsocket. A user able to perform ioctl2 cal...

Kernel: kvm: OOB memory write via kvm_dev_ioctl_get_cpuid

An out-of-bounds memory write issue was found in the way the Linux kernel's KVM hypervisor handled the 'KVMGETEMULATEDCPUID' ioctl2 request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use this flaw to crash the system, resulti...

Advantech WebAccess IOCTL 0x2711 BwPFile Stack-based Buffer Overflow Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability. The specific flaw exists within BwPFile.exe when invoked via IOCTL 0x2711. The issue results from the lack of proper...

CVE-2020-15479

An issue was discovered in PassMark BurnInTest through 9.1, OSForensics through 7.1, and PerformanceTest through 10. The driver's IOCTL request handler attempts to copy the input buffer onto the stack without checking its size and can cause a buffer overflow. This could lead to arbitrary Ring-0...

Buffer overflow

An issue was discovered in PassMark BurnInTest through 9.1, OSForensics through 7.1, and PerformanceTest through 10. The driver's IOCTL request handler attempts to copy the input buffer onto the stack without checking its size and can cause a buffer overflow. This could lead to arbitrary Ring-0...

Remote code execution

An issue was discovered in PassMark BurnInTest through 9.1, OSForensics through 7.1, and PerformanceTest through 10. The kernel driver exposes IOCTL functionality that allows low-privilege users to read and write to arbitrary Model Specific Registers MSRs. This could lead to arbitrary Ring-0 code...

CVE-2016-2064

sound/soc/msm/qdsp6v2/msm-audio-effects-q6-v2.c in the MSM QDSP6 audio driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center QuIC Android contributions for MSM devices and other products, allows attackers to cause a denial of service buffer over-read or possibly have unspecified...

Microsoft Azure Sphere asynchronous ioctl denial-of-service vulnerability

Summary A denial-of-service vulnerability exists in the asynchronous ioctl functionality of Microsoft Azure Sphere 20.05. A sequence of specially crafted ioctl calls can cause a denial of service. An attacker can write a shellcode to trigger this vulnerability. Tested Versions Microsoft Azure...

CVE-2020-14331

A flaw was found in the Linux kernel’s implementation of the invert video code on VGA consoles when a local attacker attempts to resize the console, calling an ioctl VTRESIZE, which causes an out-of-bounds write to occur. This flaw allows a local user with access to the VGA console to crash the...

CVE-2020-13753

The bubblewrap sandbox of WebKitGTK and WPE WebKit, prior to 2.28.3, failed to properly block access to CLONENEWUSER and the TIOCSTI ioctl. CLONENEWUSER could potentially be used to confuse xdg-desktop-portal, which allows access outside the sandbox. TIOCSTI can be used to directly execute comman...

kernel: use-after-free in drivers/bluetooth/hci_ldisc.c

A flaw was found in the Linux kernel's implementation of the HCI UART driver. A local attacker with access permissions to the Bluetooth device can issue an ioctl, which triggers the hciuartsetproto function in drivers/bluetooth/hcildisc.c. The flaw in this function can cause memory corruption or ...

kernel: denial of service via ioctl call in network tun handling

A flaw was found in the Linux kernel's implementation of networking tunnel device ioctl. A local attacker can cause a denial of service NULL pointer dereference and panic via an ioctl TUNSETIFF call with a dev name containing a / character...
