    cpufreq: pmac32-cpufreq: Fix refcount leak bug

    In the Linux kernel, the following vulnerability has been resolved: cpufreq: pmac32-cpufreq: Fix refcount leak bug In pmac_cpufreq_init_MacRISC3(), we need to add corresponding of_node_put() for the three node pointers whose refcount have been incremented by of_find_node_by_name().

    net: sfp: fix memory leak in sfp_probe()

    In the Linux kernel, the following vulnerability has been resolved: net: sfp: fix memory leak in sfp_probe() sfp_probe() allocates a memory chunk from sfp with sfp_alloc(). When devm_add_action() fails, sfp is not freed, which leads to a memory leak. We should use devm_add_action_or_reset() instead of devm_add_action().

    pinctrl: aspeed: Fix potential NULL dereference in aspeed_pinmux_set_mux()

    In the Linux kernel, the following vulnerability has been resolved: pinctrl: aspeed: Fix potential NULL dereference in aspeed_pinmux_set_mux() pdesc could be null but still dereference pdesc->name and it will lead to a null pointer access. So we move a null check before dereference.

    ASoC: Intel: sof_sdw: handle errors on card registration

    In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: sof_sdw: handle errors on card registration If the card registration fails, typically because of deferred probes, the device properties added for headset codecs are not removed, which leads to kernel oopses in driver bind/unbind tests. We already clean-up the device properties when the card is removed, this code can be moved as a helper and called upon card registration errors.

    ASoC: rt7*-sdw: harden jack_detect_handler

    In the Linux kernel, the following vulnerability has been resolved: ASoC: rt7*-sdw: harden jack_detect_handler Realtek headset codec drivers typically check if the card is instantiated before proceeding with the jack detection. The rt700, rt711 and rt711-sdca are however missing a check on the card pointer, which can lead to NULL dereferences encountered in driver bind/unbind tests.

    ASoC: rt711-sdca: fix kernel NULL pointer dereference when IO error

    In the Linux kernel, the following vulnerability has been resolved: ASoC: rt711-sdca: fix kernel NULL pointer dereference when IO error The initial settings will be written before the codec probe function. But, the rt711->component doesn't be assigned yet. If IO error happened during initial settings operations, it will cause the kernel panic. This patch changed component->dev to slave->dev to fix this issue.

    serial: 8250: Fix PM usage_count for console handover

    In the Linux kernel, the following vulnerability has been resolved: serial: 8250: Fix PM usage_count for console handover When console is enabled, univ8250_console_setup() calls serial8250_console_setup() before .dev is set to uart_port. Therefore, it will not call pm_runtime_get_sync(). Later, when the actual driver is going to take over univ8250_console_exit() is called. As .dev is already set, serial8250_console_exit() makes pm_runtime_put_sync() call with usage count being zero triggering PM usage count warning (extra debug for univ8250_console_setup(), univ8250_console_exit(), and serial8250_register_ports()): [ 0.068987] univ8250_

    In the Linux kernel, the following vulnerability has been resolved: x86/speculation: Fill RSB on vmexit for IBRS Prevent RSB underflow/poisoning attacks with RSB. While at it, add a bunch of comments to attempt to document the current state of tribal knowledge about RSB attacks and what exactly is being mitigated.

    KVM: VMX: Prevent RSB underflow before vmenter

    In the Linux kernel, the following vulnerability has been resolved: KVM: VMX: Prevent RSB underflow before vmenter On VMX, there are some balanced returns between the time the guest's SPEC_CTRL value is written, and the vmenter. Balanced returns (matched by a preceding call) are usually ok, but it's at least theoretically possible an NMI with a deep call stack could empty the RSB before one of the returns. For maximum paranoia, don't allow *any* returns (balanced or otherwise) between the SPEC_CTRL write and the vmenter. [ bp: Fix 32-bit build. ]

    In the Linux kernel, the following vulnerability has been resolved: power/reset: arm-versatile: Fix refcount leak in versatile_reboot_probe of_find_matching_node_and_match() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.

    pinctrl: ralink: Check for null return of devm_kcalloc

    In the Linux kernel, the following vulnerability has been resolved: pinctrl: ralink: Check for null return of devm_kcalloc Because of the possible failure of the allocation, data->domains might be NULL pointer and will cause the dereference of the NULL pointer later. Therefore, it might be better to check it and directly return -ENOMEM without releasing data manually if fails, because the comment of the devm_kmalloc() says "Memory allocated with this function is automatically freed on driver detach.".

    RDMA/irdma: Fix sleep from invalid context BUG

    In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix sleep from invalid context BUG Taking the qos_mutex to process RoCEv2 QP's on netdev events causes a kernel splat. Fix this by removing the handling for RoCEv2 in irdma_cm_teardown_connections that uses the mutex. This handling is only needed for iWARP to avoid having connections established while the link is down or having connections remain functional after the IP address is removed.
