Memory Handling Flaw in Linux Kernel's RDS Protocol

CVE-2026-53355

What is CVE-2026-53355?

A memory handling issue exists within the Linux kernel's RDS protocol, which may lead to undefined behavior during connection teardown processes. Specifically, the problem arises when the i_sends pointers are not cleared after a failure to allocate resources, potentially leading to the shutdown logic misinterpreting the resource state. This situation may permit attackers to exploit stale pointers, raising concerns about system stability and resource integrity during partial startups and repeated shutdown attempts. Proper error handling measures should be implemented to prevent mismanagement of allocated resources.
