kernel: PCI/DOE: Fix destroy_work_on_stack() race

A race condition flaw was found in the Linux kernel's PCI Data Object Exchange DOE implementation. The destroyworkonstack function is called after signaling completion, creating a race where the work struct can go out of scope before being destroyed. This triggers debug object warnings when...

kernel: cifs: Fix lost destroy smbd connection when MR allocate failed

A memory leak flaw was found in the Linux kernel's CIFS SMB Direct implementation. When memory region MR allocation fails during SMB Direct connection setup, the smbddestroy function returns early without cleaning up the connection info structure, resulting in a memory leak...

kernel: iommufd: IOMMUFD_DESTROY should not increase the refcount

A race condition was identified in the iommufd subsystem of the Linux kernel where the IOMMUFDDESTROY command incorrectly increments an object’s reference count without holding the expected exclusive synchronization destroyrwsem. This violates the assumption that temporary reference count...
