Technical description

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

scsi: pm8001: Fix tag leaks on error

In pm8001_chip_set_dev_state_req(), pm8001_chip_fw_flash_update_req(),

pm80xx_chip_phy_ctl_req() and pm8001_chip_reg_dev_req() add missing calls

to pm8001_tag_free() to free the allocated tag when pm8001_mpi_build_cmd()

fails.

Similarly, in pm8001_exec_internal_task_abort(), if the chip ->task_abort

method fails, the tag allocated for the abort request task must be

freed. Add the missing call to pm8001_tag_free().

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
