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.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/17e6ad484dea5ddf1c4a3d6ec77a5929161234de","tags":[]},{"url":"https://git.kernel.org/stable/c/18e5e0ec0e9282c897e2aa81a3e43ccaee03b003","tags":[]},{"url":"https://git.kernel.org/stable/c/47a5cecca925ceb175d5adf712e667acf78f475f","tags":[]},{"url":"https://git.kernel.org/stable/c/9b26b54861ce05307d39a54ddedddf8747419614","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
