CVE-2025-39841

CVE-2025-39841 is a Linux kernel vulnerability affecting the SCSI lpfc path in the deferred receive path, causing a use-after-free due to an incorrect buffer release/clear order. The issue arises because the code freed the RQ buffer before clearing the context pointer under the lock, while other ...
