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 ...

CVE-2026-46023

CVE-2026-46023 is a Linux kernel vulnerability in dm-mirror where create_dirty_log() could bypass argc checks due to an unsigned add of 2 + param_count, allowing an out-of-bounds read in argv when param_count is near UINT_MAX. The root cause is an overflow in argument count calculation before val...
