"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nxsk: Fix fragment node deletion to prevent buffer leak\n\nAfter commit b692bf9a7543 (\"xsk: Get rid of xdp_buff_xsk::xskb_list_node\"),\nthe list_node field is reused for both the xskb pool list and the buffer\nfree list, this causes a buffer leak as described below.\n\nxp_free() checks if a buffer is already on the free list using\nlist_empty(&xskb->list_node). When list_del() is used to remove a node\nfrom the xskb pool list, it doesn't reinitialize the node pointers.\nThis means list_empty() will return false even after the node has been\nremoved, causing xp_free() to incorrectly skip adding the buffer to the\nfree list.\n\nFix this by using list_del_init() instead of list_del() in all fragment\nhandling paths, this ensures the list node is reinitialized after removal,\nallowing the list_empty() to work correctly."
