Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue relates to a null pointer dereference error within the
coda-bit.c file of the drivers/media/platform/chips-media module in the Linux kernel. The kmalloc function may return a null pointer, and a check for this condition was missing. This could allow an attacker to cause a denial of service. The fix involves adding a check for the return value of kmalloc to prevent dereferencing a null pointer, similar to other checks already in place.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
