FreeBSD -- Use-after-free in device pager page list

Problem Description: When msyncMSINVALIDATE is called on a mapping of an unmanaged device object, the physical pages in the mapping range are marked invalid but remain in the pager's page list. A subsequent page fault will cause the fault handler to re-insert the page into the object's list. This...

CVE-2026-53323

A flaw was found in the Linux kernel's Distributed Switch Architecture DSA subsystem. Redundant locking operations within the DSA conduit ethtool wrappers can lead to a deadlock. A local attacker can exploit this by using the ethtool -i command, causing the system to become unresponsive and...

CVE-2026-53322

A flaw was found in the Linux kernel's vfio/pci subsystem. During device shutdown, an improper order of operations in cleaning up Direct Memory Access Buffers DMABUFs before disabling the function creates a brief window. In this window, a device's Base Address Registers BARs could still be access...

The vulnerability of the io_poll_remove() function in the io_uring/poll.c module of the Linux kernel’s asynchronous I/O interface allows a attacker to cause a service failure.

The vulnerability of the iopollremove function in the iouring/poll.c module of the Linux kernel’s asynchronous I/O interface involves a lack of checking for the return value. Exploiting this vulnerability could allow an attacker to cause a service failure...
