CVE-2024-53042 – ipv4: ip_tunnel: Fix suspicious RCU usage warning in ip_tunnel_init_flow()

In the Linux kernel, the following vulnerability has been resolved: ipv4: ip_tunnel: Fix suspicious RCU usage warning in ip_tunnel_init_flow() There are code paths from which the function is called without holding the RCU read lock, resulting in a suspicious RCU usage warning [1]. Fix by using l3mdev_master_upper_ifindex_by_index() which will acquire the RCU read lock before calling l3mdev_master_upper_ifindex_by_index_rcu().

CVE-2024-50304 – ipv4: ip_tunnel: Fix suspicious RCU usage warning in ip_tunnel_find()
https://notcve.org/view.php?id=CVE-2024-50304
In the Linux kernel, the following vulnerability has been resolved: ipv4: ip_tunnel: Fix suspicious RCU usage warning in ip_tunnel_find() The per-netns IP tunnel hash table is protected by the RTNL mutex and ip_tunnel_find() is only called from the control path where the mutex is taken. Add a lockdep expression to hlist_for_each_entry_rcu() in ip_tunnel_find() in order to validate that the mutex is held and to silence the suspicious RCU usage warning [1].

In the Linux kernel, the following vulnerability has been resolved: HID: core: zero-initialize the report buffer Since the report buffer is used by all kinds of drivers in various ways, let's zero-initialize it during allocation to make sure that it can't be ever used to leak kernel memory via specially-crafted report. • https://git.kernel.org/stable/c/27ce405039bfe6d3f4143415c638f56a3df77dca https://git.kernel.org/stable/c/b2b6cadad699d44a8a5b2a60f3d960e00d6fb3b7 https://git.kernel.org/stable/c/fe6c9b48ebc920ff21c10c50ab2729440c734254 https://git.kernel.org/stable/c/e7ea60184e1e88a3c9e437b3265cbb6439aa7e26 https://git.kernel.org/stable/c/3f9e88f2672c4635960570ee9741778d4135ecf5 https://git.kernel.org/stable/c/d7dc68d82ab3fcfc3f65322465da3d7031d4ab46 https://git.kernel.org/stable/c/05ade5d4337867929e7ef664e7ac8e0c734f1aaf https://git.kernel.org/stable/c/1884ab3d22536a5c14b17c78c2ce76d17 •
