What is CVE-2025-68253?

A memory management vulnerability in the Linux kernel has been identified, specifically within the page allocation mechanism. This issue arises when the function 'add_stack_record_to_list()' is invoked in contexts that do not support proper locking, which can lead to ineffective handling of stack records. The vulnerability was found during fuzz testing (syzbot) and could potentially affect memory operations, leading to instability in the affected systems. Resolution has been implemented to prevent spinning in the 'add_stack_record_to_list()' function under non-locking conditions, enhancing the reliability of memory management.
