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...

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 – Vulnerability in Linux, Linux 5.10

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...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: binder: a check for offset alignment was added in bindergetobject. Commit 6d98eb95b450 “binder: avoid potential data leakage when copying txn” introduced changes to the way binder objects are copied. As a result, the offset...

Astra Linux – Vulnerability in 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...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: RISCV: Misaligned – Restricts user access to kernel memory. The rawcopyto,fromuser function does not call accessok, allowing userspace to access any virtual memory address...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: fixed the uninit-value in caifseqpktsendmsg When nrsegs equals zero in iovecfromuser, the object msg-msgiter.iov contains uninitialized stack memory in caifseqpktsendmsg, which is defined in syssendmsg. Therefore, we cannot...

Astra Linux – Vulnerability in 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 – Vulnerability in Linux, 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...
