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

Description The Linux kernel contains a buffer overflow vulnerability in the iommu/omap module, specifically within the omap2 iommu dump ctx() function. The issue arises from insufficient checks on the len variable before writing to a buffer, potentially leading to a buffer overflow if the bytes value is less than 32. Additionally, the code uses snprintf() instead of scnprintf(), which returns the number of bytes that would have been copied instead of the number of bytes actually copied.

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