Astra Linux - уязвимость в linux-5.10, linux

In the Linux kernel, the following vulnerability has been resolved: powerpc/rtas: Avoid device tree lookups in rtasosterm. rtasosterm is called during panic. Its behavior depends on several conditions in the /rtas node of the device tree; traversing these nodes involves locking and changes to loc...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: x86/cpu: The X86CR4FRED bit was removed from the CR4 pinned bits mask. The commit in “Fixes” added the FRED CR4 bit to the CR4 pinned bits mask, so that whenever other processes modify CR4, that bit remains set. This is a perfect...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Tracing: The “Drain deferred trigger” operation is freed if kthread creation fails. Registration of boot-time triggers may fail before the trigger-data cleanup is completed. If a kthread exists, deferring the “Drain deferred...

Astra Linux - уязвимость в u-boot

The U-Boot 2022.01 has a Buffer Overflow issue...

Astra Linux - уязвимость в 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 - уязвимость в u-boot

The U-Boot versions from 2016.09 to 2019.07-rc4 can memset too much data while reading a crafted ext4 filesystem. This results in a stack buffer overflow, potentially leading to code execution...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: Tracing: Ring-buffer: A fix was made to check the length of events before using them. Check the length of events before adding them for accessing the next index in rbreaddatabuffer. Since this function is used to validate possibl...

Astra Linux - уязвимость в u-boot

A issue was discovered in Das U-Boot during the period from 2019.07. There is a stack-based buffer overflow in the nfshandler reply helper function: rpclookupreply...

Astra Linux - уязвимость в u-boot

A issue was discovered in Das U-Boot during the period from 2019.07. There is an unbounded memcpy operation with a failed length check at nfsreadreply, when calling storeblock in the NFSv3 case...

Astra Linux - уязвимость в grub2

A out-of-bounds write flaw was discovered in grub2’s NTFS filesystem driver. This issue may allow an attacker to present a specially crafted NTFS filesystem image, resulting in corruption of grub’s heap metadata. In some cases, the attack may also corrupt the UEFI firmware heap metadata. As a...

Astra Linux - уязвимость в u-boot

A carefully crafted self-referential DOS partition table will cause all Das U-Boot versions up to 2019.07-rc4 to infinitely recur, causing the stack to grow indefinitely. This could lead to a system crash or the overwriting of other data...

Astra Linux - уязвимость в u-boot

Integer overflows in memory allocation in Das U-Boot before 2025.01-rc1 occur due to a crafted squashfs filesystem using sbrk, request2size, or because ptrdifft is mishandled on x8664...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: x86/kexec: added a sanity check on the previous kernel’s ima kexec buffer. When the second-stage kernel is booted via kexec with a limiting command line such as “mem=”, the physical range that contains the carried-over IMA...

Astra Linux - уязвимость в u-boot

A issue was discovered in Das U-Boot during the period from 2019.07. There is an unbounded memcpy operation with an unvalidated length at nfsreadlinkreply in the “else” block, after calculating the new path length...

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

Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority...

Astra Linux - уязвимость в u-boot

The U-Boot until 2020.01 allows attackers to bypass verified boot restrictions and subsequently boot arbitrary images by providing a crafted FIT image to a system configured to boot the default configuration...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2. When reading the name of a symbolic link from a UFS filesystem, grub2 fails to validate the string length provided as input. This lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and potentially allowing an attacker to...

Astra Linux - уязвимость в grub2

A crafted 16-bit grayscale PNG image may lead to an out-of-bounds write in the heap area. An attacker may exploit this to cause heap data corruption or, ultimately, arbitrary code execution and circumvent secure boot protections. This issue is highly complex to exploit; an attacker needs to perfo...
