CVE-2024-36930

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue is related to a null pointer dereference within the spi sync() function in the Linux kernel. This occurs when spi sync() is called with a non-empty queue and the same spi message is reused, leading to the complete callback for the message remaining set while the context is cleared. As a result, a null pointer dereference happens when the callback is invoked from spi finalize current message(). The fix involves setting message->complete to NULL when the transfer is complete.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
