Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fixed an out-of-bounds write in kfdeventpageset. The kfdeventpageset function writes KFDSIGNALEVENTLIMIT 8 bytes via memset, without checking the buffer size parameter. This allows unprivileged userspace to trigger an...

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

In the Linux kernel, the following vulnerabilities have been resolved: kobjectuevent: Fixed issues related to OOB access within zapmodaliasenv. The zapmodaliasenv function incorrectly calculates the size of the memory block to be moved. This can lead to OOB out-of-band memory access issues if the...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the Linux kernel. A use-after-free occurred in the way the console subsystem utilized ioctls KDGKBSENT and KDSKBSENT. A local user could exploit this flaw to gain access to memory beyond its intended scope. The most significant threat posed by this vulnerability is to dat...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol RDP, released under the Apache license. In affected versions, a missing offset validation may lead to an Out Of Bound Read error in the gdimultiopaquerect function. Specifically, there is no code to validate whether the value...

Astra Linux – Vulnerability in WebKit2GTK

A vulnerability related to out-of-bounds reads has been addressed through improved input validation. This issue is fixed in iOS 14.8, iPadOS 14.8, tvOS 15, watchOS 8, iOS 15, and iPadOS 15. Processing a maliciously crafted audio file may lead to the disclosure of restricted memory...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bounds: Use the correct number of bits for power-of-two CONFIGNRCPUS The function bitsper rounds up to the next power of two when a power-of-two value is passed to it. This can cause crashes on some machines and configurations...

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: jfs: added a check to prevent array-index-out-of-bounds in dbAdjTree. When the value of lp is 0 at the beginning of the for loop, it will become negative during the next assignment, and we should take appropriate measures to avoi...

Astra Linux – Vulnerability in xwayland, xorg-server

A buffer overflow vulnerability was discovered in X.Org and Xwayland. The code in XkbVModMaskText allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and will copy the data regardless of the siz...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: fbdev: Fixed an out-of-bounds write in fastimageblit. This issue occurs when a user-space program calls ioctl FBIOPUTCON2FBMAP by passing the console number and the frame buffer number. Ideally, this maps the console to the frame...

Astra Linux – Vulnerability in Linux, Linux 5.10

In various setup methods of the USB gadget subsystem, there is a possibility of unauthorized writing due to an incorrect flag check. This could lead to a local escalation of privileges without the need for additional execution privileges. User interaction is not required for exploitation. Product...

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: arm64: cacheinfo: Avoid out-of-bounds write to the cacheinfo array The loop that detects/populates cache information already includes a check on the array size. However, it does not take into account cache levels with separate...

Astra Linux – Vulnerability in Squid

In versions 4.14 and 5.x through 5.0.5, in some configurations, the Squid vulnerability allows information disclosure due to an out-of-bounds read in the WCCP protocol data. This vulnerability can be exploited as part of a chain for remote code execution, as there is no one to stop such attacks...

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: libceph: makes decodepool more resilient against corrupted osdmaps. If the osdmap is maliciously corrupted in such a way that the encoded length of the cephpgpool envelope is less than what is expected for a particular encoding...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free remote desktop protocol library and client. In affected versions, there is an out-of-bound read in the ZGFX decoder component of FreeRDP. A malicious server can trick a FreeRDP-based client into reading out-of-bound data and attempting to decode it, potentially leading to a cras...

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: Softwarenodegetreferenceargs: A OOB check was corrected. Softwarenodegetreferenceargs attempts to retrieve the @index-th element. The property value requires at least index + 1 sizeofref bytes. However, this condition cannot be...
