Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the drivers/md/dm-ioctl.c file of the Linux kernel, up to version 6.7.1, copyparams may attempt to allocate more than INTMAX bytes, resulting in a crash due to the absence of the paramkernel-datasize check. This issue is related to ctlioctl...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: btrfs: Fixed a use-after-free after failing to create a snapshot. In ioctl.c’s createsnapshot function, we allocate a pending snapshot structure and then attach it to the transaction’s list of pending snapshots. After that, we ca...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/amdgpu: Refactored amdgpugemvaioctl to handle last fence updates and timeline management v4. This commit simplifies the amdgpugemvaioctl function by introducing the following key updates: - Moved the logic for managing the...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: gpio: Prevent potential speculation leaks in gpiodevicegetdesc The userspace may trigger a speculative read of an address outside the gpio descriptor array. Users can do this by calling gpioioctl with an offset that is out of...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: Video: fbdev: arkfb – Fixed a divide-by-zero bug in arksetpixclock Since the user can control the arguments of ioctl from the user space, there may be situations where a divide-by-zero bug occurs. For example, in the file...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: cifs: preventing incorrect output lengths in smb2ioctlqueryinfo When calling smb2ioctlqueryinfo with smbqueryinfo::flags=PASSTHRUFSCTL and smbqueryinfo::outputbufferlength=0, the following value of 0x10 will be returned. c buffer...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: dm ioctl: prevents potential Spectre v1 exploits. It seems that cmd could be a Spectre v1 exploit, as it is provided by a user and used as an array index. This vulnerability prevents the contents of kernel memory from being leake...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/panfrost: Fixed the issue where GEM handle creation was subject to ref counting. Previously, panfrostgemcreatewithhandle would return a BO, but only with a reference to the handle. User space could theoretically guess this...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Prevent potential UAF Use After Free issues during group creation. This commit addresses the issue where a malicious user space could potentially alter the handle of a group and attempt to call the GROUPDESTROY ioctl...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: validate userq input args. This will assist in validating the userq input arguments and rejecting invalid userq requests during IOCTLs...

GHSA-FJQ3-FFVR-VM46 OpenTelemetry eBPF Instrumentation: Java TLS ioctl kprobe allows kernel memory disclosure

Summary The Java TLS ioctl probe reads user-controlled ioctl pointers with bpfproberead instead of bpfprobereaduser. An instrumented local process can therefore point OBI at kernel memory and cause that memory to be copied into telemetry. Details The vulnerable path is in...

PT-2026-41788

Name of the Vulnerable Software and Affected Versions OpenTelemetry eBPF Instrumentation versions prior to 0.9.0 Description The Java TLS ioctl probe incorrectly uses the bpf probe read function instead of bpf probe read user when reading user-controlled ioctl pointers. This occurs within the do...

CVE-2025-52532

A race condition in the MxGPU-Virtualization driver’s ioctl path caused by concurrent unsynchronized access to the global variable amdgvcmd in an unlocked ioctl handler could be exploited by an attacker to trigger a heap-based buffer overflow, potentially resulting in denial-of-service within the...

CVE-2025-54517

Out of bounds write in AMD AMDGVCMDGETDIAGDATA ioctl handler could allow a local user to escalate privileges via remote code execution...

CVE-2025-52532

A race condition in the MxGPU-Virtualization driver’s ioctl path is caused by concurrent unsynchronized access to the global variable amdgv_cmd in an unlocked ioctl handler. This can be exploited locally to trigger a heap-based buffer overflow, potentially causing denial-of-service within the vul...
