https://notcve.org/view.php?id=CVE-2024-27046
In the Linux kernel, the following vulnerability has been resolved: nfp: flower: handle acti_netdevs allocation failure The kmalloc_array() in nfp_fl_lag_do_work() will return null, if the physical memory has run out. As a result, if we dereference the acti_netdevs, the null pointer dereference bugs will happen. This patch adds a check to judge whether allocation failure occurs. If it happens, the delayed work will be rescheduled and try again. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nfp: flor: manejar el error de asignación de acti_netdevs El kmalloc_array() en nfp_fl_lag_do_work() devolverá nulo, si la memoria física se ha agotado. Como resultado, si eliminamos la referencia a acti_netdevs, se producirán errores de desreferencia del puntero nulo. Este parche agrega una verificación para juzgar si se produce una falla en la asignación. • https://git.kernel.org/stable/c/bb9a8d031140f186d13d82f57b0f5646d596652f https://git.kernel.org/stable/c/d746889db75a76aeee95fb705b8e1ac28c684a2e https://git.kernel.org/stable/c/3b1e8a617eb0f4cdc19def530047a95b5abde07d https://git.kernel.org/stable/c/928705e341010dd910fdece61ccb974f494a758f https://git.kernel.org/stable/c/0d387dc503f9a53e6d1f6e9dd0292d38f083eba5 https://git.kernel.org/stable/c/c9b4e220dd18f79507803f38a55d53b483f6c9c3 https://git.kernel.org/stable/c/408ba7fd04f959c61b50db79c983484312fea642 https://git.kernel.org/stable/c/c8df9203bf22c66fa26e8d8c7f8ce181c •

CVSS: -EPSS: 0%CPEs: 9EXPL: 0CVE-2024-27043 – media: edia: dvbdev: fix a use-after-free
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: 4EXPL: 0CVE-2024-27042 – drm/amdgpu: Fix potential out-of-bounds access in 'amdgpu_discovery_reg_base_init()'
https://notcve.org/view.php?id=CVE-2024-27042
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix potential out-of-bounds access in 'amdgpu_discovery_reg_base_init()' The issue arises when the array 'adev->vcn.vcn_config' is accessed before checking if the index 'adev->vcn.num_vcn_inst' is within the bounds of the array. The fix involves moving the bounds check before the array access. This ensures that 'adev->vcn.num_vcn_inst' is within the bounds of the array before it is used as an index. Fixes the below: drivers/gpu/drm/amd/amdgpu/amdgpu_discovery.c:1289 amdgpu_discovery_reg_base_init() error: testing array offset 'adev->vcn.num_vcn_inst' after use. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amdgpu: corrige el posible acceso fuera de los límites en 'amdgpu_discovery_reg_base_init()'. El problema surge cuando se accede a la matriz 'adev->vcn.vcn_config' antes de verificar si el El índice 'adev->vcn.num_vcn_inst' está dentro de los límites de la matriz.
