If a\ndescriptor slot was reused while it still held a stale true from\na previous SKB (possible when tx_spb_ring_full() underreported\nfullness), bcmasp_tx_reclaim() would see last == true mid-SKB and\ncall dev_consume_skb_any() prematurely, freeing the sk_buff while\nits remaining fragments were still in flight.\n\nUnconditionally clear txcb->last before the conditional set so every\ndescriptor slot starts from a known false state regardless of what a\nprior transmission left behind.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
