The version of kernel installed on the remote host is prior to 5.4.294-212.419. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2025-103 advisory.

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

    scsi: target: Fix WRITE_SAME No Data Buffer crash

    In newer version of the SBC specs, we have a NDOB bit that indicates thereis no data buffer that gets     written out. If this bit is set using commandslike sg_write_same --ndob we will crash in     target_core_iblock/file'sexecute_write_same handlers when we go to access the se_cmd->t_data_sgbecause its     NULL.

    This patch adds a check for the NDOB bit in the common WRITE SAME codebecause we don't support it. And, it     adds a check for zero SG elements ineach handler in case the initiator tries to send a normal WRITE SAME     withno data buffer. (CVE-2022-21546)
