Vulnerability from github – Published: 2024-04-10 21:30 – Updated: 2026-06-01 18:31

Details

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

scsi: ufs: core: Improve SCSI abort handling

The following has been observed on a test setup:

WARNING: CPU: 4 PID: 250 at drivers/scsi/ufs/ufshcd.c:2737 ufshcd_queuecommand+0x468/0x65c Call trace: ufshcd_queuecommand+0x468/0x65c scsi_send_eh_cmnd+0x224/0x6a0 scsi_eh_test_devices+0x248/0x418 scsi_eh_ready_devs+0xc34/0xe58 scsi_error_handler+0x204/0x80c kthread+0x150/0x1b4 ret_from_fork+0x10/0x30

That warning is triggered by the following statement:

WARN_ON(lrbp->cmd);

Fix this warning by clearing lrbp->cmd from the abort handler.

Severity

5.5 (Medium)
