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 – 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...

In the Linux kernel, the following vulnerabilities have been resolved: f2fs: fixed to avoid a use-after-free in f2fsstopgcthread. syzbot reports a f2fs bug as follows: dumpstack lib/dumpstack.c:88 inline dumpstacklvl+0x241/0x360 lib/dumpstack.c:114 printreport+0xe8/0x550 mm/kasan/report.c:491...

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...

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, 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 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 – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: video: fbdev: arkfb: Fixed a divide-by-zero bug in arksetpixclock Since the user can control the arguments of the ioctl function from the user space, there are special cases where a divide-by-zero bug may occur. For example, in:...

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...
