CVE-2022-49121 Information

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().
