  "details": "In the Linux kernel, the following vulnerability has been resolved:  net: usb: ax88179_178a: fix skb leak in ax88179_tx_fixup()  When the interface has NETIF_F_SG enabled and skb_linearize() fails in ax88179_tx_fixup(), the function returns NULL without freeing the skb.  usbnet_start_xmit() treats a NULL return from tx_fixup() as a drop (info-\u003eflags does not set FLAG_MULTI_PACKET for this driver), jumping to the \"drop\" label where it does `if (skb) dev_kfree_skb_any(skb)`. Because tx_fixup() returned NULL, the local skb variable in usbnet_start_xmit() is NULL, so the original skb is never freed — a memory leak on every TX frame whose linearization fails (i.e. under memory pressure).  Free the skb before returning, matching the error handling already used for the pskb_expand_head() failure path in the same function.",
