In the Linux kernel, the following vulnerability has been resolved:[EOL][EOL]net: fix skb leak in __skb_tstamp_tx()[EOL][EOL]Commit 50749f2dd685 ("tcp/udp: Fix memleaks of sk and zerocopy skbs with[EOL]TX timestamp.") added a call to skb_orphan_frags_rx() to fix leaks with[EOL]zerocopy skbs. But it ended up adding a leak of its own. When[EOL]skb_orphan_frags_rx() fails, the function just returns, leaking the skb[EOL]it just cloned. Free it before returning.[EOL][EOL]This bug was discovered and resolved using Coverity Static Analysis[EOL]Security Testing (SAST) by Synopsys, Inc.
