AI risk analysis

Summary: The flaw allows overwriting of a user buffer with a larger sense length than intended, posing a risk of data corruption or leakage.
Exploitability: Exploitation requires a user with low privileges and access to the affected scsi device, making it moderately exploitable.
Blast radius: If exploited, the vulnerability could lead to data corruption or unauthorized access to sensitive information.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to the Linux kernel version 6.1.11 or later.

NVD description

In the Linux kernel, the following vulnerability has been resolved: scsi: bsg: Cap io_uring sense copy to max_response_len Completion copied scmd->sense_len to the user response buffer without honoring max_response_len. After a valid sense, the midlayer sets sense_len to the real length (up to SCSI_SENSE_BUFFERSIZE), so a smaller user buffer was overrun.
