Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A race condition exists in the net: ethernet: cortina driver within the gmac rx() function. The socket buffer (SKB) used to assemble packets from fragments was implemented as a static local variable. Because the Gemini hardware features two ethernet ports, simultaneous activity on both ports can lead to race conditions when assembling packets.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
