在 Linux 内核中，以下漏洞已得到修复： scsi: target: iscsi：修复因中止 WRITE_PENDING 命令导致的挂起问题 当 LUN_RESET 中止处于 TRANSPORT_WRITE_PENDING 状态的 WRITE 命令时，target 核心会将命令标记为 CMD_T_ABORTED，并等待前端完成处理。 如果发起者随后发送剩余的数据输出（dataout）PDU， 会捕获这些数据负载，若该序列为最终序列则停止 dataout 定时器，并最终丢弃（dump）这些数据。然而，iSCSI

Vulnerability Title
scsi: target: iscsi: Fix hang for aborted WRITE_PENDING commands
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Fix hang for aborted WRITE_PENDING commands When a LUN_RESET aborts a WRITE command that is in the TRANSPORT_WRITE_PENDING state, the target core sets CMD_T_ABORTED and waits for the frontend to finish processing. If the initiator subsequently sends the remaining dataout PDUs, __iscsit_check_dataout_hdr() catches the payload, stops the dataout timer if the sequence is final and finally dumps the data. However, the iSCSI target doesn't trigger the completion process for these aborted commands. Because of this, the abort path hangs indefinitely in target_put_cmd_and_wait(), leading to a deadlocked target worker thread. Fix this by explicitly calling target_complete_cmd() when the final dataout PDU is received for an aborted WRITE command. target_complete_cmd() detects the CMD_T_ABORTED flag and cleanly routes the command into target_abort_work, allowing the abort completion to successfully unblock.
