out-of-bounds access in sound/soc/sof/topology.c

Hi, I'm running 5.10.111 LTS, so if this has been fixed already then we definitely want to cherry pick the fix for -stable. Anonymous union in this struct is of zero size /* generic control data */ struct sof_ipc_ctrl_data { struct sof_ipc_reply rhdr; uint32_t comp_id; /* control access and data type */ uint32_t type; /**< enum sof_ipc_ctrl_type */ uint32_t cmd; /**< enum sof_ipc_ctrl_cmd */ uint32_t index; /**< control index for comps > 1 control */ /* control data - can either be appended or DMAed from host */ struct sof_ipc_host_buffer buffer; uint32_t num_elems; /**< in array elems or bytes for data type */ uint32_t elems_remaining; /**< elems remaining if sent in parts */ uint32_t msg_index; /**< for large messages sent in parts */ /* reserved for future use */ uint32_t reserved[6]; /* control data - add new types if needed */ union { /* channel values can be used by volume type controls */ struct sof_ipc_ctrl_value_chan chanv[0]; /* component values used by routing controls like mux, mixer */ struct sof_ipc_ctrl_value_comp compv[0]; /* data can be used by binary controls */ struct sof_abi_hdr data[0]; }; } __packed; sof_ipc_ctrl_value_chan and sof_ipc_ctrl_value_comp are of the same size - 8 bytes, while sof_abi_hdr is much larger - _at least_ 32 bytes (`__u32 data[0]` in sof_abi_hdr suggest that there should be more payload after header). But they all contribute 0 to sizeof(sof_ipc_ctrl_data). Now control data allocations looks as follows scontrol->size = struct_size(scontrol->control_data, chanv, le32_to_cpu(mc->num_channels)); scontrol->control_data = kzalloc(scontrol->size, GFP_KERNEL); Which is sizeof(sof_ipc_ctrl_data) + mc->num_channels * sizeof(sof_ipc_ctrl_value_chan) For some reason it uses sizeof(sof_ipc_ctrl_value_chan), which is not the largest member of the union. And this is where the problem is: in order to make control->data.FOO loads and stores legal we need mc->num_channels to be of at least 4. So that sizeof(sof_ipc_ctrl_data) + mc->num_channels * sizeof(sof_ipc_ctrl_value_chan) 92 + 4 * 8 will be the same as sizeof(sof_ipc_ctrl_data) + sizeof(sof_abi_hdr). 92 + 32 Otherwise scontrol->control_data->data.FOO will access nearby/foreign slab object. And there is at least one such memory access. In sof_get_control_data(). wdata[i].pdata = wdata[i].control->control_data->data; *size += wdata[i].pdata->size; pdata->size is at offset 8, but if, say, mc->num_channels == 1 then we allocate only 8 bytes for pdata, so pdata->size is 4 bytes outside of allocated slab object. Thoughts?

[PATCH] ASoC: Intel: avs: Depend on CONFIG_ACPI
by Amadeusz Sławiński 26 Apr '22

26 Apr '22

Apparently the assumption that driver can build without ACPI was too optimistic as avs selects SND_SOC_ACPI which requires working ACPI implementation. So depend on ACPI without COMPILE_TEST alternative.

[PATCH V3 2/2] ASoC: max98396: add amplifier driver
by Ryan Lee 26 Apr '22

26 Apr '22

This series of patches adds support for Analog Devices MAX98396 mono amplifier with IV sense. The device provides a PCM interface for audio data and a standard I2C interface for control data communication. This driver also supports MAX98397 which is a variant of MAX98396 with wide input supply range. Signed-off-by: Ryan Lee <ryan.lee.analog(a)gmail.com> Reported-by: kernel test robot <lkp(a)intel.com> --- Changes from v1: : Fixed DAI format configuration issue. BCLK/FRSYNC polarity configuration was inappropriate. : max98396_mux_put function return 1 if the value changed. Otherwise the function return 0 or -EINVAL; : Modified wrong amp POR(Power On Register) value in max98396_reg.
