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

Description A memory leak occurs in the octeontx2-af driver due to RX/TX flow-control bitmaps rx fc pfvf bmap and tx fc pfvf bmap being allocated by the cgx lmac init() function but not released by the cgx lmac exit() function. This issue is triggered when unbinding and rebinding the driver, leading to unreferenced objects in memory.
