Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel related to the 8250 serial driver. When the
PSLVERR RESP EN parameter is set to 1, the device can generate an error response when attempting to read an empty Receive Buffer Register (RBR) while the FIFO is enabled. This can lead to a system panic when another CPU is accessing the UART. The issue occurs due to a race condition during UART access, specifically within the dw8250 check lcr() and dw8250 force idle() functions.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
