Overview

CVE-2024-50292 is a medium-severity vulnerability affecting linux linux_kernel. It was published on November 19, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

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.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
