In the Linux kernel, the following vulnerability has been resolved: media: saa7164: fix cleanup on resource allocation failure saa7164_dev_setup() adds the device to the global saa7164_devlist before requesting the PCI BAR memory regions. If get_resources() fails, saa7164_dev_setup() decrements the device count and returns an error, but leaves the device on saa7164_devlist. The probe error path…

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: edif: Fix NULL pointer deref in RX SA delete check qla_chk_edif_rx_sa_delete_pending() obtains the SCSI command via GET_CMD_SP(sp) and immediately dereferences cmd->sc_data_direction.

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix cs84xx use-after-free on host teardown qla84xx_put_chip() drops the last reference to ha->cs84xx and frees it via __qla84xx_chip_release() without clearing ha->cs84xx. During teardown it ran before scsi_remove_host(), which is what removes the 84xx_fw_version host sysfs attribute. A concurrent read of that att…
