Description

A flaw was found in the media: stm32: dcmi component of the Linux kernel. Improper error handling in the probe() function can lead to a null pointer dereference. This issue occurs because dma_release_channel() is called before the dcmi->dma_chan variable is properly assigned, potentially allowing a local attacker to cause a denial of service (DoS) due to system instability or crashes. Additionally, other error handling bugs could result in memory leaks.
