CVE-2024-43893

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue arises when calling ioctl TIOCSSERIAL with an invalid baud base, resulting in uartclk being zero. This leads to a divide by zero error in uart get divisor(). To prevent this, the check for uartclk being zero in uart set info() needs to be done before other settings are made. The vulnerability can be exploited through the ioctl function, specifically the TIOCSSERIAL command, which can cause a divide by zero error in the uart get divisor() function.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
