CVE-2026-46063

The CVE-2026-46063 issue affects the Linux kernel with x86 shadow stack (shstk) handling of sigreturn. Root cause: during a shadow-stack sigframe read, the kernel previously held the mmap lock while verifying VMA flags to distinguish shadow stack memory. A page fault during this read could trigge...

CVE-2026-46040 inotify: fix watch count leak when fsnotify_add_inode_mark_locked() fails

In the Linux kernel, the following vulnerability has been resolved: inotify: fix watch count leak when fsnotifyaddinodemarklocked fails When fsnotifyaddinodemarklocked fails in inotifynewwatch, the error path calls inotifyremovefromidr but does not call decinotifywatches to undo the preceding...

CVE-2026-46036 vfio/cdx: Serialize VFIO_DEVICE_SET_IRQS with a per-device mutex

In the Linux kernel, the following vulnerability has been resolved: vfio/cdx: Serialize VFIODEVICESETIRQS with a per-device mutex vfiocdxsetmsitrigger reads vdev-configmsi and operates on the vdev-cdxirqs array based on its value, but provides no serialization against concurrent VFIODEVICESETIRQS...

In the Linux kernel, the following vulnerability has been resolved: vfio/cdx: Serialize VFIODEVICESETIRQS with a per-device mutex vfiocdxsetmsitrigger reads vdev-configmsi and operates on the vdev-cdxirqs array based on its value, but provides no serialization against concurrent VFIODEVICESETIRQS...

CVE-2026-46036

The CVE covers a race in the Linux kernel vfio/cdx driver where concurrent VFIO_DEVICE_SET_IRQS ioctls can observe inconsistent state of config_msi and cdx_irqs, leading to use-after-free of the cdx_irqs array. A per-device mutex (cdx_irqs_lock) is added to struct vfio_cdx_device and is acquired ...
