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...

Astra Linux – Vulnerability in Linux, Linux 5.10

A kernel information leak flaw was identified in the scsiioctl function in drivers/scsi/scsiioctl.c within the Linux kernel. This flaw allows a local attacker with special user privileges CAPSYSADMIN or CAPSYSRAWIO to cause confidentiality issues...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

A use-after-free flaw was discovered in the Linux kernel’s SGI GRU driver. This flaw arises from the way the grufileunlockedioctl function is called by the user, resulting in a failure in the grucheckchipletassignment function. This flaw allows a local user to cause a system crash or potentially...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: cifs: preventing incorrect output lengths in smb2ioctlqueryinfo When calling smb2ioctlqueryinfo with smbqueryinfo::flags=PASSTHRUFSCTL and smbqueryinfo::outputbufferlength=0, the following value of 0x10 will be returned. c buffer...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the drivers/md/dm-ioctl.c file of the Linux kernel, up to version 6.7.1, copyparams may attempt to allocate more than INTMAX bytes, resulting in a crash due to the absence of the paramkernel-datasize check. This issue is related to ctlioctl...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Locking external INTx masking operations Masking operations through changes to the config space for DisINTx may cause races with INTx configuration changes made via ioctl. Create wrappers that add locking mechanisms for...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: gpio: Prevent potential speculation leaks in gpiodevicegetdesc The userspace may trigger a speculative read of an address outside the gpio descriptor array. Users can do this by calling gpioioctl with an offset that is out of...

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...

Astra Linux – Vulnerability in Flatpak

Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. Versions prior to 1.10.8, 1.12.8, 1.14.4, and 1.15.4 contain a vulnerability similar to CVE-2017-5226, but it involves the use of the TIOCLINUX ioctl command instead of TIOCSTI. If a Flatpak...
