CVE-2026-64289

A flaw was found in the Linux kernel. In the iommufd component, the iommufdhwptinvalidate function allows a local user to provide excessively large values for entrynum and entrylen during cache invalidation. This can lead to a Denial of Service DoS by causing the system to become unresponsive...

CVE-2026-64334

A flaw was found in the Linux kernel's digiacceleport USB serial driver. This vulnerability occurs when a USB device using the driver is disconnected, and operations such as opening or closing the device are happening concurrently. Persistent errors in sending out-of-band OOB write Universal Seri...

CVE-2026-64474

A flaw was found in the Linux kernel's Virtual Function I/O VFIO device migration feature. The vfiomiggetnextstate function, responsible for managing device migration states, contains an infinite loop. This occurs when processing certain blocked transitions, causing the system to hold a driver...

UBUNTU-CVE-2026-64415

In the Linux kernel, the following vulnerability has been resolved: mm/swap: add condresched in swapreclaimfullclusters to prevent softlockup We hit a real softlockup in an internal stress test environment. The workload was LTP memory/swap stress on a large arm64 machine, with 320 CPUs, about 1TB...

CVE-2026-64474

The CVE-2026-64474 issue affects the Linux kernel VFIO path, specifically vfio_mig_get_next_state() which walks vfio_from_fsm_table[] and could spin forever when encountering an ERROR sentinel (STOP_COPY arcs to ERROR). The root cause was an unaccounted ERROR sentinel in the skip loop, allowing a...

EUVD-2026-49001

In the Linux kernel, the following vulnerability has been resolved: iommufd: Set upper bounds on cache invalidation entrynum and entrylen iommufdhwptinvalidate takes a user-controlled entrynum and entrylen, each bounded only by U32MAX. An entrylen beyond the kernel's struct size makes the copy...

CVE-2026-64289

CVE-2026-64289 (Linux kernel) affects the iommufd path where iommufd_hwpt_invalidate() uses user-controlled entry_num and entry_len. The issue arises because these values were previously only bounded by U32_MAX, allowing excessively large inputs to drive the backend invalidation loop and cause pr...

CVE-2026-53304

A flaw was found in the Linux kernel's SCSI generic sg module. A local user could bypass the intended size restrictions for the defreservedsize module parameter. By setting this parameter to an invalid value and then attempting to open a SCSI generic device, the system can experience a soft locku...
