In the Linux kernel, the following vulnerability has been resolved: eth: sungem: remove .ndo_poll_controller to avoid deadlocks Erhard reports netpoll warnings from sungem: netpoll_send_skb_on_dev(): eth0 enabled interrupts in poll (gem_start_xmit+0x0/0x398) WARNING: CPU: 1 PID: 1 at net/core/netpoll.c:370 netpoll_send_skb+0x1fc/0x20c gem_poll_controller() disables interrupts, which may sleep. We can't sleep in netpoll, it has interrupts disabled completely. Strangely, gem_poll_controller() doesn't even poll the completions, and instead acts as if an interrupt has fired so it just schedules NAPI and exits. None of this has been necessary for years, since netpoll invokes NAPI directly. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: eth: sungem: elimine .ndo_poll_controller para evitar interbloqueos Erhard informa advertencias de netpoll desde sungem: netpoll_send_skb_on_dev(): eth0 habilitó interrupciones en la encuesta (gem_start_xmit+0x0/0x398) ADVERTENCIA: CPU: 1 PID: 1 en net/core/netpoll.c:370 netpoll_send_skb+0x1fc/0x20c gem_poll_controller() desactiva las interrupciones, que pueden dormir. No podemos dormir en netpoll, tiene las interrupciones desactivadas por completo. Curiosamente, gem_poll_controller() ni siquiera sondea las finalizaciones y, en cambio, actúa como si se hubiera disparado una interrupción, por lo que simplemente programa NAPI y sale. • https://git.kernel.org/stable/c/fe09bb619096a0aa139210748ddc668c2dbe2308 https://git.kernel.org/stable/c/e22b23f5888a065d084e87db1eec639c445e677f https://git.kernel.org/stable/c/fbeeb55dbb33d562149c57e794f06b7414e44289 https://git.kernel.org/stable/c/476adb3bbbd7886e8251d3b9ce2d3c3e680f35d6 https://git.kernel.org/stable/c/5de5aeb98f9a000adb0db184e32765e4815d860b https://git.kernel.org/stable/c/faf94f1eb8a34b2c31b2042051ef36f63420ecce https://git.kernel.org/stable/c/6400d205fbbcbcf9b8510157e1f379c1d7e2e937 https://git.kernel.org/stable/c/ac0a230f719b02432d8c7eba7615ebd69 •

https://notcve.org/view.php?id=CVE-2024-38596
In the Linux kernel, the following vulnerability has been resolved: af_unix: Fix data races in unix_release_sock/unix_stream_sendmsg A data-race condition has been identified in af_unix. In one data path, the write function unix_release_sock() atomically writes to sk->sk_shutdown using WRITE_ONCE. However, on the reader side, unix_stream_sendmsg() does not read it atomically. Consequently, this issue is causing the following KCSAN splat to occur: BUG: KCSAN: data-race in unix_release_sock / unix_stream_sendmsg write (marked) to 0xffff88867256ddbb of 1 bytes by task 7270 on cpu 28: unix_release_sock (net/unix/af_unix.c:640) unix_release (net/unix/af_unix.c:1050) sock_close (net/socket.c:659 net/socket.c:1421) __fput (fs/file_table.c:422) __fput_sync (fs/file_table.c:508) __se_sys_close (fs/open.c:1559 fs/open.c:1541) __x64_sys_close (fs/open.c:1541) x64_sys_call (arch/x86/entry/syscall_64.c:33) do_syscall_64 (arch/x86/entry/common.c:?) entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:130) read to 0xffff88867256ddbb of 1 bytes by task 989 on cpu 14: unix_stream_sendmsg (net/unix/af_unix.c:2273) __sock_sendmsg (net/socket.c:730 net/socket.c:745) ____sys_sendmsg (net/socket.c:2584) __sys_sendmmsg (net/socket.c:2638 net/socket.c:2724) __x64_sys_sendmmsg (net/socket.c:2753 net/socket.c:2750 net/socket.c:2750) x64_sys_call (arch/x86/entry/syscall_64.c:33) do_syscall_64 (arch/x86/entry/common.c:?) • https://git.kernel.org/stable/c/1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 https://git.kernel.org/stable/c/fca6072e1a7b1e709ada5604b951513b89b4bd0a https://git.kernel.org/stable/c/de6641d213373fbde9bbdd7c4b552254bc9f82fe https://git.kernel.org/stable/c/4d51845d734a4c5d079e56e0916f936a55e15055 https://git.kernel.org/stable/c/9aa8773abfa0e954136875b4cbf2df4cf638e8a5 https://git.kernel.org/stable/c/8299e4d778f664b31b67cf4cf3d5409de2ecb92c https://git.kernel.org/stable/c/0688d4e499bee3f2749bca27329bd128686230cb https://git.kernel.org/stable/c/a4c88072abcaca593cefe70f90e9d3707 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2024-38593
In the Linux kernel, the following vulnerability has been resolved: net: micrel: Fix receiving the timestamp in the frame for lan8841 The blamed commit started to use the ptp workqueue to get the second part of the timestamp. And when the port was set down, then this workqueue is stopped. But if the config option NETWORK_PHY_TIMESTAMPING is not enabled, then the ptp_clock is not initialized so then it would crash when it would try to access the delayed work. So then basically by setting up and then down the port, it would crash. The fix consists in checking if the ptp_clock is initialized and only then cancel the delayed work. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: net: micrel: Se corrigió la recepción de la marca de tiempo en el framework para lan8841. El commit culpable comenzó a usar la cola de trabajo ptp para obtener la segunda parte de la marca de tiempo. • https://git.kernel.org/stable/c/cc75549548482ed653c23f212544e58cb38ea980 https://git.kernel.org/stable/c/3ddf170e4a604f5d4d9459a36993f5e92b53e8b0 https://git.kernel.org/stable/c/3fd4282d5f25c3c97fef3ef0b89b82ef4e2bc975 https://git.kernel.org/stable/c/64a47cf634ae44e92be24ebc982410841093bd7b https://git.kernel.org/stable/c/aea27a92a41dae14843f92c79e9e42d8f570105c https://access.redhat.com/security/cve/CVE-2024-38593 https://bugzilla.redhat.com/show_bug.cgi?id=2293380 • CWE-457: Use of Uninitialized Variable •
