Advantech WebAccess IOCTL 0x1138B 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 the handling of IOCTL 0x1138B. The issue results from the lack of proper validation ...

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 use-after-free flaw was found in kernel/trace/ringbuffer.c in Linux kernel. There was a race problem in traceopen and resize of cpu buffer running parallely on different cpus, may cause a denial of service problem DOS. This flaw could even allow a local attacker with special use...

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...
