Astra Linux – Vulnerability in Linux 5.10

A double-free flaw was discovered in the Linux kernel’s TUN/TAP device driver functionality, particularly in how a user registers the device when the registernetdevice function fails with the NETDEVREGISTER notifier. This flaw allows a local user to crash the system or potentially escalate their...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

An integer overflow vulnerability was discovered in the vmwgfx driver, located in the vmxgfxexecbuf.c file within the GPU component of the Linux kernel. The vulnerability affects device files such as '/dev/dri/renderD128 or Dxxx'. This flaw allows a local attacker with a user account on the syste...

Astra Linux – Vulnerability in Git

Git is a distributed revision control system. Versions of Git prior to 2.37.1, 2.36.2, 2.35.4, 2.34.4, 2.33.4, 2.32.3, 2.31.4, and 2.30.5 were vulnerable to privilege escalation on all platforms. A careless user could still be affected by the issue reported in CVE-2022-24765, for example, when...

Astra Linux – Vulnerability in open-vm-tools

VMware Tools 12.0.0, 11.x.y, and 10.x.y contains a local privilege escalation vulnerability. A malicious actor with local non-administrative access to the guest OS can escalate privileges as a root user in the virtual machine...

Astra Linux – Vulnerability in Redis

Redis is an in-memory database that persists data on disk. By exploiting vulnerabilities in the Lua script execution environment, an attacker with access to Redis prior to versions 7.0.0 or 6.2.7 can inject Lua code that will execute with the potentially higher privileges of another Redis user. T...

Astra Linux – Vulnerability in Linux, Linux 5.10

A flaw was discovered in the sctpmakestrresetreq function within the net/sctp/smmakechunk.c file, located in the SCTP network protocol in the Linux kernel. This flaw involves attempting to use more buffer space than is allocated, which triggers a BUGON issue, resulting in a denial of service DOS...

Astra Linux – Vulnerability in Linux

In the binderreleasework function of binder.c, there is a potential use-after-free issue due to improper locking. This could lead to a local escalation of privileges in the kernel, without the need for additional execution privileges. User interaction is not required for exploitation. Product:...

Netlogon RPC Elevation of Privilege Vulnerability...

Astra Linux – Vulnerability in xorg-server

A vulnerability was discovered in X.Org. This security flaw occurs because the handler for the XvdiSelectVideoNotify request may write to memory after it has been freed. This issue can lead to local privileges escalation on systems where X is used...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the context of dm-verity-target.c, there is a potential way to modify read-only files due to a missing permission check. This could lead to a local escalation of privileges, as System execution privileges are required. User interaction is not necessary for exploiting this vulnerability. Produc...

Astra Linux – Vulnerability in xorg-server

A vulnerability was discovered in X.Org. This security flaw arises because the XkbCopyNames function left a dangling pointer pointing to freed memory, allowing for out-of-bounds memory access during subsequent XkbGetKbdByName requests. This issue can lead to local privileges escalation on systems...

Astra Linux – Vulnerability in freeipa

A privilege escalation from the host to the domain vulnerability was identified in the FreeIPA project. By default, the FreeIPA package fails to validate the uniqueness of the krbCanonicalName for the admin account, allowing users to create services with the same canonical name as the REALM admin...

Astra Linux – Vulnerability in Intel Microcode

Improper input validation in some IntelR TDX module software prior to version 1.5.05.46.698 may allow a privileged user to potentially enable privilege escalation through local access...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the virtio-fs shared file system daemon virtiofsd of QEMU. The new ‘xattrmap’ option may cause the ‘security.capability’ xattr in the guest to not be dropped when writing files, potentially allowing a modified, privileged executable to be executed within the guest. In rar...

Astra Linux – Vulnerability in Linux

A race condition in Linux kernel SCTP sockets net/sctp/socket.c before version 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If the sctpdestroysock function is called without using the socknetsk-sctp.addrwqlock lock, an element...

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

A use-after-free vulnerability exists in the netfilter component of the Linux kernel’s code, specifically the nftables module. This vulnerability can be exploited to achieve local privilege escalation. Due to a race condition between the netlink control plane transaction and the garbage collectio...

Astra Linux – Vulnerability in Chromium

Insufficient policy enforcement in Cryptohome’s Google Chrome version prior to 88.0.4324.96 allowed a local attacker to perform OS-level privilege escalation through a crafted file...

Astra Linux – Vulnerability in Linux 5.15

A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to gain local privilege escalation.
