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

Description The Linux kernel contains a flaw in the octeontx2-af driver related to the handling of MAC blocks during RVU driver initialization. The driver incorrectly assumes contiguity of LMAC and CGX blocks, leading to potential kernel panics when accessing these blocks with their IDs, particularly with the introduction of new MAC blocks like CN10K RPM and CN10KB RPM USX. The issue is addressed by adding validation checks before accessing CGX and lmac. The crash occurs in the cgx lmac read function, called from rvu program channels.

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