 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:ASoC: stm32: spdifrx: fix dma channel release in stm32_spdifrx_removeIn case of error when requesting ctrl_chan DMA channel, ctrl_chan is notnull. So the release of the dma channel leads to the following issue:[    4.879000] st,stm32-spdifrx 500d0000.audio-controller:dma_request_slave_channel error -19[    4.888975] Unable to handle kernel NULL pointer dereferenceat virtual address 000000000000003d[...][    5.096577] Call trace:[    5.099099]  dma_release_channel+0x24/0x100[    5.103235]  stm32_spdifrx_remove+0x24/0x60 [snd_soc_stm32_spdifrx][    5.109494]  stm32_spdifrx_probe+0x320/0x4c4 [snd_soc_stm32_spdifrx]To avoid this issue, release channel only if the pointer is valid.

CVE-2024-50292

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

ASoC: stm32: spdifrx: fix dma channel release in stm32_spdifrx_remove

In case of error when requesting ctrl_chan DMA channel, ctrl_chan is not
null. So the release of the dma channel leads to the following issue:
[    4.879000] st,stm32-spdifrx 500d0000.audio-controller:
dma_request_slave_channel error -19
[    4.888975] Unable to handle kernel NULL pointer dereference
at virtual address 000000000000003d
[...]
[    5.096577] Call trace:
[    5.099099]  dma_release_channel+0x24/0x100

[    5.109494]  stm32_spdifrx_probe+0x320/0x4c4 [snd_soc_stm32_spdifrx]

To avoid this issue, release channel only if the pointer is valid.

The Linux kernel CVE team has assigned CVE-2024-50292 to this issue.
