The current version of pkexec does not proper...

Astra Linux – Vulnerability in Linux

A buffer overflow attack in fbcon in the Linux kernel before version 5.9.7 could be exploited by local attackers to read privileged information or potentially cause the kernel to crash. This issue is identified as CID-3c4e0dff2095. This vulnerability arises because the KDFONTOPCOPY function in...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the Linux kernel in versions prior to 5.9-rc6. When changing the screen size, an out-of-bounds memory write can occur, leading to memory corruption or a denial of service. Due to the nature of the flaw, privilege escalation cannot be completely ruled out...

Astra Linux – Vulnerability in open-vm-tools

A malicious actor who has been granted “Guest Operation Privileges” https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-security/GUID-6A952214-0E5E-4CCF-9D2A-90948FF643EC.html can potentially elevate their privileges if the target virtual machine has been assigned a more privileged “Guest Alias...

Astra Linux – Vulnerability in Linux, Linux 5.10

A random memory access flaw was discovered in the Linux kernel’s GPU i915 kernel driver functionality. This flaw allows a local user to crash the system or escalate their privileges on the system...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the CAN BCM networking protocol within the Linux kernel. A local attacker can exploit this flaw in the CAN subsystem to corrupt memory, cause the system to crash, or escalate privileges. This race condition in the net/can/bcm.c file of the Linux kernel allows for local...

Astra Linux – Vulnerability in Linux, Linux 5.10

A vulnerability was discovered in btrfsalloctreeb in fs/btrfs/extent-tree.c within the Linux kernel, due to an improper lock operation in btrfs. This flaw allows a user with local privileges to cause a denial of service DOS due to a deadlock issue...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In multiple functions of iouring.c, there is a possibility of kernel memory corruption due to improper locking. This could lead to a local escalation of privileges in the kernel, as execution privileges are required. User interaction is not necessary for exploiting this vulnerability...

Astra Linux – Vulnerability in Linux, Linux 5.10

A stack overflow flaw was discovered in the Linux kernel’s TIPC protocol functionality. This flaw occurs when a user sends a packet containing malicious content, where the number of domain member nodes exceeds the allowed limit of 64. This flaw allows a remote user to crash the system or...

Astra Linux – Vulnerability in Apache2

A privilege escalation bug in various modules of Apache HTTP 2.4.66 and earlier allows local .htaccess authors to read files with the privileges of the httpd user. Users are recommended to upgrade to version 2.4.67, which fixes this issue...

Astra Linux – Vulnerability in ofono

oFono SimToolKit Heap-based Buffer Overflow Privilege Escalation Vulnerability. This vulnerability allows local attackers to execute arbitrary code on affected installations of oFono. An attacker must first obtain the ability to execute code on the target modem in order to exploit this...

Astra Linux – Vulnerability in Linux 5.10

In ioidentitycow of iouring.c, there is a potential way to corrupt memory due to a use after free. This could lead to a local escalation of privileges, as the exploit requires system execution privileges. User interaction is not required for exploitation. Product: Android Versions: Android kernel...

Astra Linux – Vulnerability in ntfs-3g

NTFS-3G versions prior to 2021.8.22 may experience a heap buffer overflow when a specially crafted NTFS attribute is set up using the function ntfsattrsetupflag. This could allow code execution and an escalation of privileges...

Astra Linux – Vulnerability in Intel Microcode

A protection mechanism failure in some third- and fourth-generation IntelR XeonR processors, when using IntelR SGX or IntelR TDX, may allow a privileged user to potentially enable privilege escalation through local access...

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

A use-after-free vulnerability exists in the Linux kernel’s net/sched:clsfw component, which can be exploited to achieve local privilege escalation. When the fwchange function is called on an existing filter, the entire tcfresult struct is always copied into the new instance of the filter. This...

Astra Linux – Vulnerability in ofono

oFono SMS Decoder Stack-based Buffer Overflow Privilege Escalation Vulnerability. This vulnerability allows local attackers to execute arbitrary code on affected installations of oFono. An attacker must first obtain the ability to execute code on the target modem in order to exploit this...
