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

In the Linux kernel, the following vulnerability has been resolved: usb: typec: ucsi: The numconnectors field is incorrectly handled. The UCSI specification states that the numconnectors field consists of 7 bits, with the 8th bit reserved and should be set to zero. Some faulty firmware has been...

Astra Linux – Vulnerability in u-boot

In Das U-Boot through 2022.07-rc5, an integer signedness error and resulting stack-based buffer overflow occur in the “i2c md” command, which allows for the corruption of the return address pointer of the doi2cmd function...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: arm64: hibernate: Fixed the level3 translation fault in swsuspsave On arm64 machines, swsuspsave fails if it attempts to access MEMBLOCKNOMAP memory ranges. This issue can be reproduced in QEMU using UEFI when booting with...

Astra Linux – Vulnerability in grub2

A flaw was discovered in command/gpg. In some scenarios, hooks created by loaded modules are not removed when the related module is unloaded. This flaw allows an attacker to force grub2 to call the hooks once the module that registered them was unloaded, resulting in a use-after-free vulnerabilit...

Astra Linux – Vulnerability in grub2

The “read” command is used to read the keyboard input from the user. While reading, the input length is stored as a 32-bit integer value. This value is then used to reallocate the line buffer to accommodate the next character. During this process, if the line is long enough, it’s possible for thi...

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

In the Linux kernel, the following vulnerability has been resolved: media: venus: protection against spurious interrupts during probing. Ensure that the interrupt handler is initialized before the interrupt is registered. If the IRQ is registered before hficreate, it’s possible that an interrupt...

Astra Linux – Vulnerability in u-boot

In “Das U-Boot through 2020.01”, a double-free operation was detected in the cmd/gpt.c file’s dorenamegptparts function. Double-freeing can lead to a “write-what-where” condition, allowing an attacker to execute arbitrary code. NOTE: This vulnerability was introduced when attempting to fix a memo...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: Driver Core: Fixed the interaction between waitfordeviceprobe and deferredprobetimeout. The mounting of NFS rootfs timed out when deferredprobetimeout was non-zero 1. This occurred because the ipautoconfig initcall timed out...
