https://notcve.org/view.php?id=CVE-2023-52656
In the Linux kernel, the following vulnerability has been resolved: io_uring: drop any code related to SCM_RIGHTS This is dead code after we dropped support for passing io_uring fds over SCM_RIGHTS, get rid of it. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: io_uring: elimina cualquier código relacionado con SCM_RIGHTS. Este es un código inactivo después de que dejamos de admitir el paso de io_uring fds sobre SCM_RIGHTS, deshazte de él. A flaw was found in the Linux kernel that addresses the removal of dead code related to `SCM_RIGHTS` support within the `io_uring`. This code was deemed unnecessary after the kernel dropped the ability to pass `io_uring` file descriptors over `SCM_RIGHTS`. • https://git.kernel.org/stable/c/cfb24022bb2c31f1f555dc6bc3cc5e2547446fb3 https://git.kernel.org/stable/c/a6771f343af90a25f3a14911634562bb5621df02 https://git.kernel.org/stable/c/d909d381c3152393421403be4b6435f17a2378b4 https://git.kernel.org/stable/c/a3812a47a32022ca76bf46ddacdd823dc2aabf8b https://git.kernel.org/stable/c/88c49d9c896143cdc0f77197c4dcf24140375e89 https://git.kernel.org/stable/c/6e5e6d274956305f1fc0340522b38f5f5be74bdb https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html https://access.redhat.com/security/cve/CVE-2023 •

In the Linux kernel, the following vulnerability has been resolved: firewire: nosy: ensure user_length is taken into account when fetching packet contents Ensure that packet_buffer_get respects the user_length provided. If the length of the head packet exceeds the user_length, packet_buffer_get will now return 0 to signify to the user that no data were read and a larger buffer size is required. Helps prevent user space overflows. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: firewire: nosy: asegúrese de que se tenga en cuenta la longitud de usuario al recuperar el contenido del paquete. Asegúrese de que paquete_buffer_get respete la longitud de usuario proporcionada. • https://git.kernel.org/stable/c/67f34f093c0f7bf33f5b4ae64d3d695a3b978285 https://git.kernel.org/stable/c/7b8c7bd2296e95b38a6ff346242356a2e7190239 https://git.kernel.org/stable/c/cca330c59c54207567a648357835f59df9a286bb https://git.kernel.org/stable/c/79f988d3ffc1aa778fc5181bdfab312e57956c6b https://git.kernel.org/stable/c/4ee0941da10e8fdcdb34756b877efd3282594c1f https://git.kernel.org/stable/c/1fe60ee709436550f8cfbab01295936b868d5baa https://git.kernel.org/stable/c/539d51ac48bcfcfa1b3d4a85f8df92fa22c1d41c https://git.kernel.org/stable/c/38762a0763c10c24a4915feee722d7aa6 •

https://notcve.org/view.php?id=CVE-2024-27399
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: l2cap: fix null-ptr-deref in l2cap_chan_timeout There is a race condition between l2cap_chan_timeout() and l2cap_chan_del(). When we use l2cap_chan_del() to delete the channel, the chan->conn will be set to null. But the conn could be dereferenced again in the mutex_lock() of l2cap_chan_timeout(). As a result the null pointer dereference bug will happen.

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Fix use-after-free bugs caused by sco_sock_timeout When the sco connection is established and then, the sco socket is releasing, timeout_work will be scheduled to judge whether the sco disconnection is timeout. The sock will be deallocated later, but it is dereferenced again in sco_sock_timeout. As a result, the use-after-free bugs will happen.

https://notcve.org/view.php?id=CVE-2023-52655
In the Linux kernel, the following vulnerability has been resolved: usb: aqc111: check packet for fixup for true limit If a device sends a packet that is inbetween 0 and sizeof(u64) the value passed to skb_trim() as length will wrap around ending up as some very large value. The driver will then proceed to parse the header located at that position, which will either oops or process some random value. The fix is to check against sizeof(u64) rather than 0, which the driver currently does. The issue exists since the introduction of the driver. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: usb: aqc111: verifique el paquete para corregir el límite verdadero Si un dispositivo envía un paquete que está entre 0 y sizeof(u64), el valor pasado a skb_trim() como longitud se ajustará terminando como un valor muy grande. Luego, el controlador procederá a analizar el encabezado ubicado en esa posición, lo que procesará algún valor aleatorio. La solución es compararlo con sizeof(u64) en lugar de 0, como hace actualmente el controlador. • https://git.kernel.org/stable/c/84f2e5b3e70f08fce3cb1ff73414631c5e490204 https://git.kernel.org/stable/c/d69581c17608d81824dd497d9a54b6a5b6139975 https://git.kernel.org/stable/c/46412b2fb1f9cc895d6d4036bf24f640b5d86dab https://git.kernel.org/stable/c/82c386d73689a45d5ee8c1290827bce64056dddd https://git.kernel.org/stable/c/2ebf775f0541ae0d474836fa0cf3220e502f8e3e https://git.kernel.org/stable/c/ccab434e674ca95d483788b1895a70c21b7f016a •
