Astra Linux – Vulnerability in Linux, Linux 5.10

A race condition was identified in the vtkioctl function within drivers/tty/vt/vtioctl.c in the Linux kernel. This may lead to an out-of-bounds read, as the write access to vcmode is not protected by a lock in vtioctl KDSETMDE. The primary threat of this vulnerability is data confidentiality...

vt_ioctl() Function Heap Buffer Overflow DoS

Vulnerability of the vtioctl function in the drivers/tty/vt/vtioctl.c module – The driver for supporting TTY consoles in Linux operating systems is vulnerable to integer overflow or cyclic shift attacks. Exploiting this vulnerability could allow an attacker to cause a service failure...

DEBIAN-CVE-2022-48804

In the Linux kernel, the following vulnerability has been resolved: vtioctl: fix arrayindexnospec in vtsetactivate arrayindexnospec ensures that an out-of-bounds value is set to zero on the transient path. Decreasing the value by one afterwards causes a transient integer underflow. vsa.console...

kernel: a race out-of-bound read in vt

A race problem was seen in the vtkioctl in drivers/tty/vt/vtioctl.c in the Linux kernel, which may cause an out of bounds read in vt as the write access to vcmode is not protected by lock-in vtioctl KDSETMDE. The highest threat from this vulnerability is to data confidentiality...

A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel which may cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl (KDSETMDE). The highest threat from this vulnerability is to data confidentiality.

Medium: kernel

Issue Overview: A race problem was seen in the vtkioctl in drivers/tty/vt/vtioctl.c in the Linux kernel, which may cause an out of bounds read in vt as the write access to vcmode is not protected by lock-in vtioctl KDSETMDE. The highest threat from this vulnerability is to data confidentiality...

Important: kernel

Issue Overview: A flaw was found in the Linux kernel. When reusing a socket with an attached dccpshctxccid as a listener, the socket will be used after being released leading to denial of service DoS or a potential code execution. The highest threat from this vulnerability is to data...

PT-2024-11804

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to the vt ioctl function, specifically the vt setactivate call, where the array index nospec mechanism fails to properly sanitize an out-of-bounds value, leading to ...

Linux Kernel Buffer Overflow Vulnerability

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A buffer error vulnerability exists in the Linux kernel that stems from a race condition issue in vtkioctl in drivers/tty/vt/vtioctl.c. This could result in out-of-bounds reads...

PT-2021-4205

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to a race problem in the vt k ioctl function in the Linux kernel, specifically in the drivers/tty/vt/vt ioctl.c file. This problem may cause an out of bounds read in...
