CVE-2022-49121 Detail

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().
