Astra Linux – Vulnerability in Linux

A memory-bound write flaw 1 or 2 bytes of memory was identified in the Linux kernel’s NFS subsystem, related to the way users use mirroring replication of files via NFS. A user with access to the NFS mount could potentially exploit this flaw to crash the system or escalate privileges on the syste...

Astra Linux – Vulnerability in Linux, Linux 5.10

In ipcheckmcrcu of igmp.c, there is a potential use after free due to improper locking. This could lead to a local escalation of privileges when opening and closing inet sockets, without the need for additional execution privileges. User interaction is not required for exploitation. Product:...

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

A use-after-free vulnerability exists in the netfilter component of the Linux kernel’s nftables module, which can be exploited to achieve local privilege escalation. The nftpipapowalk function does not skip inactive elements during the set walk operation, which can result in double deactivation o...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the Linux kernel. A memory use-after-free vulnerability was identified in the perf subsystem, allowing a local attacker with permission to monitor perf events, thereby corrupting memory and potentially escalating privileges. The most significant threat of this vulnerabili...

Astra Linux – Vulnerability in gdisk

In the LoadPartitionTable function of gpt.cc, there is a potential out-of-bounds write vulnerability due to a missing bounds check. This could lead to a local escalation of privileges when inserting a malicious USB device, without the need for additional execution privileges. User interaction is...

Astra Linux – Vulnerability in Linux 5.15

There is a use-after-free vulnerability in the ALSA PCM package within the Linux kernel. The SNDRVCTLIOCTLELEMREAD|WRITE32 function lacks locks that could be exploited in a use-after-free situation, potentially leading to an escalation of privileges to gain ring0 access from the system user. We...

Astra Linux – Vulnerability in Qemu

A reentrancy issue related to DMA operations led to a use-after-free error in the e1000e NIC emulation code in QEMU. This issue could allow a privileged guest user to crash the QEMU process on the host, resulting in a denial of service...

Astra Linux – Vulnerability in Linux

A use-after-free flaw was discovered in cgroup1parseparam in kernel/cgroup/cgroup-v1.c within the Linux kernel’s cgroup v1 parser. A local attacker with user privileges could exploit the fsconfig syscall parameter to escalate privileges, resulting in a container breakout and a denial of service o...

Astra Linux – Vulnerability in libhttp-daemon-perl

HTTP::Daemon is a simple HTTP server class written in Perl. Versions prior to 6.15 are vulnerable to a vulnerability that could potentially be exploited to gain privileged access to APIs or corrupt intermediate caches. It’s unclear how severe the risks are; most Perl-based applications are served...

Astra Linux – Vulnerability in Linux, Linux 5.10

A flaw was discovered in the s390 eBPF JIT mechanism within bpfjitinsn in the arch/s390/net/bpfjitcomp.c file of the Linux kernel. In this flaw, a local attacker with special user privileges can bypass the verifier, potentially leading to confidentiality issues...

Astra Linux – Vulnerability in PackageKit

PackageKit is a D-Bus abstraction layer that allows users to manage packages in a secure manner using an API that works across different distros and architectures. PackageKit, from version 1.0.2 to 1.3.4, is vulnerable to a time-of-check time-of-use TOCTOU race condition involving transaction...

Astra Linux – Vulnerability in xorg-server

A use-after-free flaw was discovered in the X.Org X server and Xwayland within the SyncChangeCounter function. A client that sets up multiple SyncCounters may cause a use-after-free when destroying those counters through a second client connection while modifying those counters. This could...

Astra Linux – Vulnerability in xorg-server

A out-of-bounds write flaw was discovered in the X.Org X server and Xwayland within DRIGetBuffers/DRIGetBuffersWithFormat. A client that requests multiple DRI2BufferBackLeft attachments and one DRI2BufferFrontLeft can trigger a out-of-bounds heap write. This vulnerability could be exploited to...

Astra Linux – Vulnerability in Linux

A use-after-free occurred in the function hcisockboundioctl of the Linux kernel’s HCI subsystem. This issue arises when the user calls ioct HCIUNBLOCKADDR, or when the call to hciunregisterdev triggers a race condition, along with the calls hcisockblacklistadd, hcisockblacklistdel, hcigetconninfo...

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

An integer coercion error was detected in the openvswitch kernel module. When there are a sufficient number of actions, while copying and reserving memory for a new action of a new flow, the reservesfasize function does not return -EMSGSIZE as expected. This could potentially lead to an...

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 nftables module, which can be exploited to achieve local privilege escalation. The nftverdictinit function allows positive values to be used as drop errors within the hook verdict. As a result, the nfhookslow...
