In the Linux kernel, the following vulnerability has been resolved: rtase: fix double free of multi-frag skb on DMA map failure In rtasestartxmit(), when the head buffer DMA mapping fails after rtasexmitfrags() has mapped all fragments, the error path clears the fragment descriptors with rtasetxclearrange(), which frees the skb through the last-frag slot and accounts txdropped. Control then falls through to the common error label, which frees the same skb a second time and counts it again. Return right after clearing the fragments when the skb owns frags; the no-frag case still drops through and frees the head skb once.
