CVE-2026-45958

The CVE-2026-45958 vulnerability affects the Linux kernel, specifically the drm/exynos vidi driver. In vidi_connection_ioctl(), the code dereferenced a user pointer directly (vidi->edid(user pointer)), enabling arbitrary kernel memory access from user space and potentially leading to privilege...

PT-2026-43825

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the vidi connection ioctl function where the vidi-edid user pointer is directly dereferenced within the kernel. This allows arbitrary kernel memory access from user spac...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the failure of zero-copy page fixing in the rdsmessagezcopyfromuser function. This failure does n...

Astra Linux - уязвимость в linux-5.10, linux, linux-5.15

In 64-bit versions of the Linux kernel, Copyfromuser does not implement uaccessbeginnospec, which allows a user to bypass the “accessok” check and pass a kernel pointer to copyfromuser. This would enable an attacker to leak sensitive information. We recommend upgrading beyond commit...

Astra Linux - уязвимость в linux

Shiftfs is a tree-based stacking file system included in Ubuntu Linux kernels. It did not handle faults that occurred during the copyfromuser function properly. This could lead to situations where resources were freed twice, or where no memory was actually freed at all. An attacker could exploit...

MetInfo weixinreply command injection

Added: 05/07/2026 Background MetInfo is an open-source content management system CMS written in PHP and MySQL developed in China. Problem A vulnerability in the weixinreply class allows remote attackers to execute arbitrary commands by sending an API request with specially crafted EventKey and...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: fixed an uninitialized value in caifseqpktsendmsg. When nrsegs equals zero in iovecfromuser, the object msg-msgiter.iov contains uninitialized stack memory, which is used in caifseqpktsendmsg. This behavior is defined in...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: netdevsim: A trailing zero was added to terminate the string in nsimnexthopbucketactivitywrite. This issue was identified by a static analyzer. We should not forget the trailing zero after copyfromuser if we will perform further...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ALSA: Timer – Do not take registermutex with copyfrom/touser. The infamous mmaplock taken during copyfrom/touser can often be problematic when it is called within another mutex, as this may lead to deadlocks. In the case of ALSA...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: AppArmor: A memory leak has been fixed in multitransactionnew. In multitransactionnew, the variable t is not freed or passed away after a failure in the copyfromusert-data, buf, size operation. This could lead to a memory leak...

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

A issue was discovered in the Linux kernel before version 5.19. In the pxa3xxgcuwrite function in drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict between sizet and int, which causes an integer overflow and bypasses the size check. Additionally, since this parameter is us...
