🛡️ AZL-74829 — kernel

CVE-2025-39841 affecting package kernel for versions less than 5.15.200.1-1

In the Linux kernel, the following vulnerability has been resolved:

scsi: lpfc: Fix buffer free/clear order in deferred receive path

Fix a use-after-free window by correcting the buffer release sequence in

the deferred receive path. The code freed the RQ buffer first and only

then cleared the context pointer under the lock. Concurrent paths (e.g.,

ABTS and the repost path) also inspect and release the same pointer under

the lock, so the old order could lead to double-free/UAF.

Note that the repost path already uses the correct pattern: detach the

pointer under the lock, then free it after dropping the lock. The

deferred path should do the same.
