CVE-2026-53996

The CVE-2026-53996 entry affects NetBSD's hdaudio(4) driver (sys/dev/hdaudio/hdaudio.c), where a missing access check on /dev/hdaudioN device nodes allows unprivileged local attackers to invoke HDAUDIO_FGRP_SETCONFIG via an IOCTL. A race between thread_stop and thread_disestablish in hdafg_detach...

CVE-2026-68184

A flaw was found in the Linux kernel's CD-ROM cdrom driver. When handling the CDROMVOLCTRL command, the mmcioctlcdromvolume function can perform an incorrect calculation of buffer length after a pointer adjustment. This leads to a stack out-of-bounds read, where 8 bytes of data beyond the intende...

CVE-2026-68275

A flaw was found in the drm/amdgpu component of the Linux kernel. A local attacker, with the ability to issue ioctl commands to the render group, could trigger a null pointer dereference by requesting mapping information for an unmapped buffer object. This could lead to a system crash, resulting ...

CVE-2026-68178

A flaw was found in the Linux kernel's NSM Network Shared Memory misc device. A local user could exploit this by opening the /dev/nsm device and then unloading the NSM module. This allows a subsequent operation ioctl on the open file descriptor to call into memory that has been deallocated,...

CVE-2026-68200

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA timer component. A lack of serialization in the userspace-driven timer utimer TRIGGER ioctl allows two threads to concurrently call sndtimerinterrupt. This race condition can lead to a use-after-free vulnerability, wher...

DEBIAN-CVE-2026-68242

In the Linux kernel, the following vulnerability has been resolved: drm/i915/gt: Fix NULL deref on schedengine alloc failure Avoid using intelcontextput before intelcontextinit in execlistscreatevirtual as the krefput inside would lead to NULL deref on the IOCTL path when schedengine allocation...

CVE-2026-68179

In the Linux kernel, the following vulnerability has been resolved: misc: nsm: only unlock nsmdev on post-lock error paths nsmdevioctl jumps to the common out label even when the initial copyfromuser fails before nsm-lock has been taken. The error path then blindly unlocks a mutex that was never...
