Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-402588)

medium Nessus Plugin ID 266950

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-402588 advisory.

 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 [ 5.103235] 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.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
