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

tcp: Fix a data-race around sysctl_tcp_probe_threshold.

While reading sysctl_tcp_probe_threshold, it can be changed concurrently. Thus, we need to add READ_ONCE() to its reader.

The Linux Kernel, the operating system core itself. Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:scsi: pm8001: Fix tag leaks on errorIn 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 callsto 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_abortmethod fails, the tag allocated for the abort request task must befreed. Add the missing call to pm8001_tag_free().(CVE-2022-49121)

In the Linux kernel, the following vulnerability has been resolved:scsi: qla2xxx: Fix scheduling while atomicThe driver makes a call into midlayer (fc_remote_port_delete) which can putthe thread to sleep. The thread that originates the call is in interruptcontext. The combination of the two trigger a crash. Schedule the call innon-interrupt context where it is more safe.kernel: BUG: scheduling while atomic: swapper/7/0/0x00010000kernel: Call Trace:kernel: <IRQ>kernel: dump_stack+0x66/0x81kernel: __schedule_bug.cold.90+0x5/0x1dkernel: __schedule+0x7af/0x960kernel: schedule+0x28/0x80kernel: schedule_timeout+0x26d/0x3b0kernel: wait_for_completion+0xb4/0x140kernel: ? wake_up_q+0x70/0x70kernel: __wait_rcu_gp+0x12c/0x160kernel: ? sdev_evt_alloc+0xc0/0x180 [scsi_mod]kernel: synchronize_sched+0x6c/0x80kernel: ? call_rcu_bh+0x20/0x20kernel: ? __bpf_trace_rcu_invoke_ca…
