Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fixed a memory leak in kfdmemdmamapuserptr. If the number of pages from the userptr BO differs from the SG BO, then the allocated memory for the SG table does not get freed before returning – this may lead to a memory...

Astra Linux – Vulnerability in Linux 5.10

Ubuntu Linux 6.8, 7.17, and 7.0 contain AppArmor SAUCE patches that, under certain circumstances, may use an uninitialized variable in notification handling code. This bug can be triggered by a non-privileged local user, and it can lead to incorrect caching of AppArmor notification responses...

Astra Linux – Vulnerability in Linux 5.10

Ubuntu Linux 6.8 includes AppArmor patches that fail to properly acquire a lock when modifying a linked list. An unprivileged local user could exploit this race condition, leading to a Use-After-Free UAF error, and, theoretically, arbitrary code execution...

Astra Linux – Vulnerability in Linux-Firmware

Improper initialization of the IntelR PROSet/Wireless and IntelR KillerTM Wi-Fi software before version 22.240 may allow an unauthenticated user to potentially enable information disclosure via adjacent access...

In the Linux kernel, the following vulnerability has been resolved: media: az6007: Fixed nullptrderef in az6007i2cxfer In az6007i2cxfer, msg is controlled by the user. When msgi.buf is null and msgi.len is zero, previous checks on msgi.buf would still be performed. Malicious data could eventually...

Astra Linux – Vulnerability in Chromium

Before version 97.0.4692.99, using "Print in Google Chrome" allowed a remote attacker to convince the user to engage in specific user interactions, thereby potentially exploiting heap corruption through a crafted HTML page...

Astra Linux – Vulnerability in Linux

An out-of-bounds memory access flaw was discovered in the x25bind function in the net/x25/afx25.c file within the Linux kernel version v5.12-rc5. A failure in the bounds check allows a local attacker with a user account on the system to access out-of-bounds memory, resulting in a system crash or...

Astra Linux – Vulnerability in Chromium

Before version 102.0.5005.61, using the "after free" feature in the Performance Manager in Google Chrome allowed a remote attacker to potentially exploit heap corruption by using a crafted HTML page, as long as that attacker could convince a user to perform certain user interactions...

Astra Linux – Vulnerability in Chromium

The use of “after free” in User Education in Google Chrome before version 102.0.5005.61 allowed an attacker who convinced a user to install a malicious extension to potentially exploit heap corruption through a crafted Chrome Extension or specific user interactions...

Astra Linux – Vulnerability in Linux 5.15

A flaw in memory writing within the Linux kernel’s UDF file system functionality was discovered. This flaw allows a user to trigger certain file operations, which in turn triggers udfwritefi. A local user could exploit this flaw to crash the system or potentially cause other malicious actions...

Astra Linux – Vulnerability in Linux 5.15

A NULL pointer dereference flaw was discovered in the Linux kernel’s AMD Sensor Fusion Hub driver. This flaw allows a local user to crash the system...

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

A use-after-free flaw was discovered in the Linux kernel’s SGI GRU driver. This flaw arises from the way the grufileunlockedioctl function is called by the user, resulting in a failure in the grucheckchipletassignment function. This flaw allows a local user to cause a system crash or potentially...

Astra Linux – Vulnerability in Linux, Linux 5.10

A non-privileged write-to-file handler flaw exists in the Linux kernel’s control groups and namespaces subsystem. This flaw allows users to gain access to certain less-privileged processes that are controlled by cgroups, even when those processes have higher-privileged parent processes. This issu...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

A use-after-free flaw was discovered in the Linux kernel’s Netfilter functionality when adding a rule with NFTARULECHAINID. This flaw allows a local user to crash or escalate their privileges on the system...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A vulnerability related to out-of-bounds memory access was discovered in the Linux kernel’s XFS file system, regarding how a user restores an XFS image after a failure with a dirty log journal. This vulnerability allows a local user to crash the system or potentially escalate their privileges on...

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

A flaw was discovered in the Linux kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a type confusion in their initialization function. While this will usually be correct, since tuntap devices require CAPNETADMIN, it may not always be the case. For example, a non-root user...

Astra Linux – Vulnerability in Linux, Linux 5.10

A race condition accessing file objects in the Linux kernel OverlayFS subsystem was identified. This occurs when users renames files using OverlayFS in a specific manner. A local user could exploit this flaw to cause the system to crash...
