https://notcve.org/view.php?id=CVE-2024-27043
In the Linux kernel, the following vulnerability has been resolved: media: edia: dvbdev: fix a use-after-free In dvb_register_device, *pdvbdev is set equal to dvbdev, which is freed in several error-handling paths. However, *pdvbdev is not set to NULL after dvbdev's deallocation, causing use-after-frees in many places, for example, in the following call chain: budget_register |-> dvb_dmxdev_init |-> dvb_register_device |-> dvb_dmxdev_release |-> dvb_unregister_device |-> dvb_remove_device |-> dvb_device_put |-> kref_put When calling dvb_unregister_device, dmxdev->dvbdev (i.e. *pdvbdev in dvb_register_device) could point to memory that had been freed in dvb_register_device. Thereafter, this pointer is transferred to kref_put and triggering a use-after-free. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: medios: edia: dvbdev: corregir un use-after-free En dvb_register_device, *pdvbdev se establece igual a dvbdev, que se libera en varias rutas de manejo de errores. • https://git.kernel.org/stable/c/b61901024776b25ce7b8edc31bb1757c7382a88e https://git.kernel.org/stable/c/d0f5c28333822f9baa5280d813124920720fd856 https://git.kernel.org/stable/c/f20c3270f3ed5aa6919a87e4de9bf6c05fb57086 https://git.kernel.org/stable/c/096237039d00c839f3e3a5fe6d001bf0db45b644 https://git.kernel.org/stable/c/0d3fe80b6d175c220b3e252efc6c6777e700e98e https://git.kernel.org/stable/c/437a111f79a2f5b2a5f21e27fdec6f40c8768712 https://git.kernel.org/stable/c/779e8db7efb22316c8581d6c229636d2f5694a62 https://git.kernel.org/stable/c/35674111a043b0482a9bc69da8850a83f •
CVSS: 5.5EPSS: 0%CPEs: 6EXPL: 0CVE-2024-27037 – clk: zynq: Prevent null pointer dereference caused by kmalloc failure
https://notcve.org/view.php?id=CVE-2024-27037
In the Linux kernel, the following vulnerability has been resolved: clk: zynq: Prevent null pointer dereference caused by kmalloc failure The kmalloc() in zynq_clk_setup() will return null if the physical memory has run out. As a result, if we use snprintf() to write data to the null address, the null pointer dereference bug will happen. This patch uses a stack variable to replace the kmalloc(). En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: clk: zynq: evita la desreferencia del puntero nulo causada por una falla de kmalloc. El kmalloc() en zynq_clk_setup() devolverá nulo si la memoria física se ha agotado. Como resultado, si usamos snprintf() para escribir datos en la dirección nula, se producirá el error de desreferencia del puntero nulo. • https://git.kernel.org/stable/c/0ee52b157b8ed88550ddd6291e54bb4bfabde364 https://git.kernel.org/stable/c/01511ac7be8e45f80e637f6bf61af2d3d2dee9db https://git.kernel.org/stable/c/8c4889a9ea861d7be37463c10846eb75e1b49c9d https://git.kernel.org/stable/c/0801c893fd48cdba66a3c8f44c3fe43cc67d3b85 https://git.kernel.org/stable/c/ca976c6a592f789700200069ef9052493c0b73d8 https://git.kernel.org/stable/c/58a946ab43501f2eba058d24d96af0ad1122475b https://git.kernel.org/stable/c/7938e9ce39d6779d2f85d822cc930f73420e54a6 • CWE-476: NULL Pointer Dereference •

In the Linux kernel, the following vulnerability has been resolved: spi: spi-mt65xx: Fix NULL pointer access in interrupt handler The TX buffer in spi_transfer can be a NULL pointer, so the interrupt handler may end up writing to the invalid memory and cause crashes. Add a check to trans->tx_buf before using it. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: spi: spi-mt65xx: corrige el acceso al puntero NULL en el controlador de interrupciones. El búfer TX en spi_transfer puede ser un puntero NULL, por lo que el controlador de interrupciones puede terminar escribiendo en la memoria no válida y causar accidentes.
