CVE-2022-50375 is a vulnerability in the Linux kernel's fsl_lpuart serial driver, affecting Linux kernel versions. It arises when the lpuart_dma_shutdown function fails to properly disable DMA use flags, leading to attempts to access deallocated DMA resources during subsequent buffer flushes. This can cause the kernel to panic, resulting in a denial-of-service. The vulnerability has a CVSS score of 5.5 (Medium), indicating a local attack vector with low attack complexity, requiring low privileges, and resulting in high impact to availability. There is no impact on confidentiality or integrity. Currently, there is no evidence of active exploitation, and no public exploit code is available on platforms like Metasploit or ExploitDB. Community discussion and media coverage for this CVE are minimal, suggesting low public awareness and attention.
