CVSS: 3.8EPSS: 0%CPEs: 4EXPL: 0CVE-2023-52584 – spmi: mediatek: Fix UAF on device remove
https://notcve.org/view.php?id=CVE-2023-52584
In the Linux kernel, the following vulnerability has been resolved: spmi: mediatek: Fix UAF on device remove The pmif driver data that contains the clocks is allocated along with spmi_controller. On device remove, spmi_controller will be freed first, and then devres , including the clocks, will be cleanup. This leads to UAF because putting the clocks will access the clocks in the pmif driver data, which is already freed along with spmi_controller. This can be reproduced by enabling DEBUG_TEST_DRIVER_REMOVE and building the kernel with KASAN. Fix the UAF issue by using unmanaged clk_bulk_get() and putting the clocks before freeing spmi_controller. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: spmi: mediatek: reparar UAF en la eliminación del dispositivo. Los datos del controlador pmif que contienen los relojes se asignan junto con spmi_controller. Al eliminar el dispositivo, primero se liberará spmi_controller y luego se limpiarán los devres, incluidos los relojes. Esto lleva a UAF porque al poner los relojes se accederá a los relojes en los datos del controlador pmif, que ya están liberados junto con spmi_controller. • https://git.kernel.org/stable/c/521f28eedd6b14228c46e3b81e3bf9b90c2818d8 https://git.kernel.org/stable/c/f8dcafcb54632536684336161da8bdd52120f95e https://git.kernel.org/stable/c/9a3881b1f07db1bb55cb0108e6f05cfd027eaf2e https://git.kernel.org/stable/c/e821d50ab5b956ed0effa49faaf29912fd4106d9 • CWE-416: Use After Free •

In the Linux kernel, the following vulnerability has been resolved: ceph: fix deadlock or deadcode of misusing dget() The lock order is incorrect between denty and its parent, we should always make sure that the parent get the lock first. But since this deadcode is never used and the parent dir will always be set from the callers, let's just remove it. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ceph: corrige el punto muerto o el código muerto por uso incorrecto de dget() El orden de bloqueo es incorrecto entre denty y su padre, siempre debemos asegurarnos de que el padre obtenga el bloqueo primero. Pero dado que este código muerto nunca se usa y el directorio principal siempre será configurado por quienes llaman, simplemente eliminémoslo. • https://git.kernel.org/stable/c/eb55ba8aa7fb7aad54f40fbf4d8dcdfdba0bebf6 https://git.kernel.org/stable/c/6ab4fd508fad942f1f1ba940492f2735e078e980 https://git.kernel.org/stable/c/e016e358461b89b231626fcf78c5c38e35c44fd3 https://git.kernel.org/stable/c/a9c15d6e8aee074fae66c04d114f20b84274fcca https://git.kernel.org/stable/c/7f2649c94264d00df6b6ac27161e9f4372a3450e https://git.kernel.org/stable/c/196b87e5c00ce021e164a5de0f0d04f4116a9160 https://git.kernel.org/stable/c/76cb2aa3421fee4fde706dec41b1344bc0a9ad67 https://git.kernel.org/stable/c/b493ad718b1f0357394d2cdecbf00a44a •

In the Linux kernel, the following vulnerability has been resolved: tomoyo: fix UAF write bug in tomoyo_write_control() Since tomoyo_write_control() updates head->write_buf when write() of long lines is requested, we need to fetch head->write_buf after head->io_sem is held. Otherwise, concurrent write() requests can cause use-after-free-write and double-free problems. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tomoyo: corrige el error de escritura UAF en tomoyo_write_control() Dado que tomoyo_write_control() actualiza head->write_buf cuando se solicita write() de líneas largas, necesitamos recuperar head->write_buf después head->io_sem se mantiene. De lo contrario, las solicitudes de escritura () simultáneas pueden causar problemas de use-after-free-write y de doble liberación. • https://git.kernel.org/stable/c/bd03a3e4c9a9df0c6b007045fa7fc8889111a478 https://git.kernel.org/stable/c/a23ac1788e2c828c097119e9a3178f0b7e503fee https://git.kernel.org/stable/c/7d930a4da17958f869ef679ee0e4a8729337affc https://git.kernel.org/stable/c/3bfe04c1273d30b866f4c7c238331ed3b08e5824 https://git.kernel.org/stable/c/2caa605079488da9601099fbda460cfc1702839f https://git.kernel.org/stable/c/6edefe1b6c29a9932f558a898968a9fcbeec5711 https://git.kernel.org/stable/c/2f03fc340cac9ea1dc63cbf8c93dd2eb0f227815 https://lists.debian.org/debian-lts-announce/2024/06/ •
