CVE-2026-68180

CVE-2026-68180: In the Linux kernel intel_th MSC output path, a reference leak occurred. intel_th_output_open() selects the output device via bus_find_device_by_devt(), which returns a device reference that must be dropped. The release path for MSC outputs, intel_th_msc_release(), only removed th...

CVE-2026-68179 misc: nsm: only unlock nsm_dev on post-lock error paths

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...

CVE-2026-68179

CVE-2026-68179 affects the Linux kernel NSM: nsm_dev_ioctl() may unlock a mutex that was never acquired when pre-lock copy_from_user() fails, risking a local DoS. A patch changes control flow to return immediately on pre-lock failures and to keep the unlock path for post-lock errors only. The vul...

CVE-2026-68178

CVE-2026-68178 concerns the Linux kernel NSM (Network Shared Memory) misc device. The root cause is that misc_open() installs file_operations with fops_get() which pins file_operations::owner, but NSM’s misc device left nsm_dev_fops.owner unset, allowing an open /dev/nsm descriptor to survive an ...
