Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: espintcp: fixed skb leaks. Several error paths now include a kfreeskb...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: dlm: Length validation in dlmsearchrsbtree was added. The len parameter in dlmdumprsbname is not validated and comes from network messages. When this parameter exceeds DLMRESNAMEMAXLEN, it may cause an out-of-bounds write in...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ALSA: scarlett2: A buffer overflow has been fixed in the configuration retrieval process. The scarlett2usbgetconfig function contains a logical error in the endianness conversion code, which can lead to buffer overflows when coun...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: xfs: removed xfsattrleafhasname The calling convention of xfsattrleafhasname is problematic because it returns a NULL buffer when xfsattr3leafread fails, a valid buffer when xfsattr3leaflookupint returns -ENOATTR or -EEXIST, and ...

Astra Linux – Vulnerability in libsoup2.4

A flaw was discovered in libsoup. An integer underflow vulnerability occurs when processing content with a zero-length resource, resulting in a buffer overread. This can allow an attacker to potentially access sensitive information or cause a denial of service at the application level...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: AppArmor: Avoid per-cpu hold underflow in aagetbuffer. When aagetbuffer retrieves data from the per-cpu list, it conditionally decreases cache-hold. If hold reaches 0 while count remains non-zero, the unsigned decrement wraps to...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: drm/panthor: Fixed UAF issues on kernel BO VA nodes. If the MMU is down, panthorvmunmaprange might return an error. We expect the page table to still be updated; if the MMU is blocked, the rest of the GPU should also be blocke...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: HID: i2c-hid: fixed a potential buffer overflow in i2chidgetreport i2chidxfer is used to read recvlen + sizeofle16 bytes of data into ihid-rawbuf. The former can originate from the user space of the hidraw driver and is bounded b...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.20.1, a global-buffer-overflow issue was observed during FreeRDP’s Base64 decoding process. The root cause appears to be implementation-defined char signedness: on Arm/AArch64 builds, plain char values are treated...

Astra Linux – Vulnerability in expat

In libexpat before version 2.7.4, the doContent function does not properly determine the buffer size bufSize, as there is no check for integer overflow during the reallocation of the tag buffer...

Astra Linux – Vulnerability in Node.js

A flaw in Node.js’s buffer allocation logic can expose uninitialized memory when allocations are interrupted, especially when using the vm module with the timeout option. Under certain timing conditions, buffers allocated using Buffer.alloc and other TypedArray instances like Uint8Array may conta...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.0, there was a buffer overflow vulnerability in freerdpbitmapdecompressplanar when SrcSize was 0. The function dereferences srcp which points to pSrcData without first verifying that SrcSize is greater than or...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: Wifi: ath11k: Fixed an issue where the RCU stall occurred during the processing of the monitor destination ring. During this process, MSDUs are retrieved from the link descriptor based on the corresponding bufid. However,...

Astra Linux – Vulnerability in gst-plugins-good1.0

GStreamer rtpqdm2depay: Heap-based Buffer Overflow and Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability, but the attack vectors...

Astra Linux – Vulnerability in binutils

A flaw was discovered in binutils. A heap-buffer-overflow vulnerability exists when processing a specially crafted XCOFF Extended Common Object File Format object file during linking. A local attacker could trick a user into processing this malicious file, which could lead to arbitrary code...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.20.1, a heap-buffer overflow occurred during drive reads when a server-controlled read length was used to read file data into an IRP output stream buffer without a hard upper limit. This allowed an oversized read ...

Astra Linux – Vulnerability in xz-utils

XZ Utils provides a general-purpose data-compression library along with command-line tools. Prior to version 5.8.3, if the lzmaindexdecoder function was used to decode an Index that contained no Records, the resulting lzmaindex would be in a state where subsequent calls to lzmaindex.Append would...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Wifi: wlcore – Ensure skbheadroom before calling skbpush. This fix prevents occasional skbunderpanic errors in wl1271txwork. In this case, the allocated headroom is less than what is actually needed typically 110 – 94 = 16 bytes...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Wifi: rtl818x: rtl8187: Fixed a potential buffer underflow in rtl8187rxcb. The rtl8187rxcb function calculates the RX descriptor header address by subtracting its size from the skbtailptr. However, it does not validate whether th...
