Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: gpib: A use-after-free occurred in the IO ioctl handlers. The IBRD, IBWRT, IBCMD, and IBWAIT ioctl handlers use a gpibdescriptor pointer after the board-biggpibmutex has been released. A concurrent IBCLOSEDEV ioctl can free the...

CVE-2026-43338

CVE-2026-43338 affects the Linux kernel with the Btrfs filesystem. The issue arises because qgroup ioctls do not reserve transaction space, allowing -ENOSPC scenarios during quota-tree updates and delayed refs, which can abort transactions and enable a DoS condition. Vendors have published adviso...

kernel: Linux kernel: Denial of Service in ATM CLIP module via infinite recursion

A flaw was found in the Linux kernel's Asynchronous Transfer Mode ATM Classical IP CLIP module. A local user can trigger an infinite recursive call in the clippush function by repeatedly calling the ioctlATMARPMKIP system call. This vulnerability occurs when the socket is closed, leading to stack...

Qualcomm Chipsets are a family of chipsets from Qualcomm Incorporated USA. A security vulnerability exists in Qualcomm Chipsets that stems from an information leak when handling IOCTL calls that are used to free a trusted VM process or open a channel without initializing the process...

The vulnerability of the Linux operating system’s kernel, related to the use of memory after it is freed, allows attackers to disclose sensitive information that should be protected.

The vulnerability of the Linux operating system’s kernel is related to the use of memory after it is freed. Exploiting this vulnerability can allow an attacker to disclose sensitive information by using system calls such as ioctls KDGKBSENT and KDSKBSENT...

UBUNTU-CVE-2018-18397

The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file if the user has read-only access to that file, and that file contains holes, related to...
