Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: comedi: A memory leak has been fixed in compatinsnlist. compatinsnlist handles the 32-bit version of the COMEDIINSNLIST ioctl function when CONFIGCOMPAT is enabled. It allocates memory to temporarily hold an array of struct...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: comedi: vmk80xx: fixed the bulk-buffer overflow issue. The driver uses buffers sized equal to the endpoint size, but it should not assume that the tx and rx buffers have the same size. A malicious device could cause the...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: comedi: The issue of using uninitialized memory in doinsnioctl and doinsnlistioctl has been fixed. syzbot reports a KMSAN kernel-infosek in doinsnioctl. A kernel buffer is allocated to hold insn-n samples each of which is an...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: comedi: niusb6501: fixed NULL dereference in command paths. The driver uses USB transfer buffers of the endpoint size, but there were no sanity checks on their sizes. This can lead to dereferencing of zero-size pointers or...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: comedi: niatmio16d: Fixed invalid cleanup after a failed attach operation. If the driver’s COMEDI “attach” handler function atmio16dattach returns an error, the COMEDI core will call the driver’s “detach” handler function...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: comedi: The dev-spinlock is reinitialized between attachments to low-level drivers. struct comedidevice is the main controlling structure for a COMEDI device created by the COMEDI subsystem. It contains a member spinlock that...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: comedi: dt2815: Hardware detection was added to prevent crashes. The dt2815 driver crashes when it is attached to I/O ports without any actual hardware present. This occurs because syzkaller or users can attach the driver to...
