cve 2024 44951

CVE-2024-44951 is a race condition vulnerability in the Linux kernel's sc16is7xx serial driver, which is used for multi-channel UART-like serial chips on embedded boards and SoCs. The bug can corrupt transmit FIFO data, causing packets received on one channel to be erroneously transmitted on another, leading to availability and integrity issues. This vulnerability was introduced by an earlier locking change and has been fixed in stable kernel trees. Discussions on WindowsForum.com cover the technical details of the flaw, its impact on cross-channel data transmission, and the necessary patches to mitigate the risk.
