In the Linux kernel, the following vulnerability has been resolved: ipv6: fix possible UAF in ip6_finish_output2() If skb_expand_head() returns NULL, skb has been freed and associated dst/idev could also have been freed. We need to hold rcu_read_lock() to make sure the dst and associated idev are alive. • https://git.kernel.org/stable/c/5796015fa968a3349027a27dcd04c71d95c53ba5 https://git.kernel.org/stable/c/ded37d03440d0ab346a8287cc2ba88b8dc90ceb0 https://git.kernel.org/stable/c/2323690eb05865a657709f4d28eb9538ea97bfc2 https://git.kernel.org/stable/c/b34c668a867ffdcf8bd8db4a36512572e82b4a15 https://git.kernel.org/stable/c/e891b36de161fcd96f12ff83667473e5067b9037 https://git.kernel.org/stable/c/3574d28caf9a09756ae87ad1ea096c6f47b6101e https://git.kernel.org/stable/c/6ab6bf731354a6fdbaa617d1ec194960db61cf3b https://git.kernel.org/stable/c/56efc253196751ece1fc535a5b582be12 •

In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix double DMA unmapping for XDP_REDIRECT Remove the dma_unmap_page_attrs() call in the driver's XDP_REDIRECT code path.
