Directory paths that contained a tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a special...

USN-8753-1 libinput vulnerability

It was discovered that libinput did not properly escape device properties. A local attacker could possibly use this issue to inject arbitrary udev properties and execute arbitrary code as root...

Astra Linux – Vulnerability in Linux

Linux Kernel Bluetooth CMTP Module Double Free Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of the Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in orde...

Astra Linux – Vulnerability in Linux, Linux 5.10

A use-after-free vulnerability was discovered in the rtsxusbmsdrvremove function in the drivers/memstick/host/rtsxusbms.c file within the memstick module of the Linux kernel. In this flaw, a local attacker with user privileges could compromise the confidentiality of system resources. This...

Astra Linux – Vulnerability in Linux 5.15

A use-after-free flaw was discovered in nfsd4sscsetupdul in fs/nfsd/nfs4proc.c within the NFS filesystem of the Linux kernel. This issue could allow a local attacker to crash the system or may lead to a kernel information leak...

Astra Linux – Vulnerability in Linux

An out-of-bounds memory access flaw was discovered in the fs/f2fs/node.c file within the f2fs module of the Linux kernel, in versions prior to 5.12.0-rc4. A failure in the bounds check allows a local attacker to gain access to out-of-bounds memory, resulting in a system crash or the leakage of...

Astra Linux – Vulnerability in libvirt

A flaw was discovered in the RPC library APIs of libvirt. The RPC server deserialization code allocates memory for arrays before performing the negative length check by the C API entry points. Passing a negative length to the gnew0 function results in a crash because the negative length is treate...

Astra Linux – Vulnerability in Python 3.7

There is a flaw in Python 3’s pydoc documentation. A local or nearby attacker who discovers or can convince another local or nearby user to start a pydoc server could access the server and use it to disclose sensitive information belonging to that user that they would not normally be able to...

Astra Linux – Vulnerability in Linux, Linux 5.10

A data leak flaw was discovered in the way of the XFSIOCALLOCSP IOCTL in the XFS filesystem, which allows for an increase in file sizes when the size is unaligned. A local attacker could exploit this flaw to leak data from the XFS filesystem that would otherwise be inaccessible to them...

Astra Linux – Vulnerability in Systemd

It was discovered that a Systemd service that uses the DynamicUser property can create a SUID/SGID binary that will be allowed to run as the transient service’s UID/GID even after the service is terminated. A local attacker could exploit this flaw to access resources that will be owned by a...

Astra Linux – Vulnerability in Systemd

The basic/unit-name.c file in systemd, prior to versions 246.15, 247.8, 248.5, and 249.1, contains a memory allocation with an excessive size value. This issue involves functions strdupa and alloca, where a pathname is controlled by a local attacker, leading to a system crash...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

A use-after-free flaw was discovered in xgenehwmonremove in drivers/hwmon/xgene-hwmon.c within the Hardware Monitoring Linux Kernel Driver xgene-hwmon. This flaw could allow a local attacker to cause the system to crash due to a race condition. This vulnerability could even lead to a situation...

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, Linux 5.10

A NULL pointer dereference flaw was discovered in the btrfsrmdevice function in fs/btrfs/volumes.c within the Linux Kernel. Triggering this bug requires CAPSYSADMIN. This flaw allows a local attacker to crash the system or leak internal kernel information. The greatest threat posed by this...

Astra Linux – Vulnerability in Linux

In the Linux kernel, from drivers/block/nbd.c up to version 5.10.12, there is a use-after-free in the nbdaddsocket function. This issue could be triggered by local attackers who have access to the nbd device. The attack occurs during I/O requests at a certain point in device setup, specifically...

Astra Linux – Vulnerability in Linux, Linux 5.10

A flaw was discovered in the Linux kernel’s KVM when attempting to set the SynIC IRQ. This issue allows a malfunctioning VMM to write to the SYNIC/STIMER MSRs, leading to a NULL pointer derefrence error. This flaw enables an unprivileged local attacker on the host to issue specific ioctl calls,...

Astra Linux – Vulnerability in Linux 5.15
