https://notcve.org/view.php?id=CVE-2024-36022
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Init zone device and drm client after mode-1 reset on reload In passthrough environment, when amdgpu is reloaded after unload, mode-1 is triggered after initializing the necessary IPs, That init does not include KFD, and KFD init waits until the reset is completed. KFD init is called in the reset handler, but in this case, the zone device and drm client is not initialized, causing app to create kernel panic. v2: Removing the init KFD condition from amdgpu_amdkfd_drm_client_create. As the previous version has the potential of creating DRM client twice. v3: v2 patch results in SDMA engine hung as DRM open causes VM clear to SDMA before SDMA init. Adding the condition to in drm client creation, on top of v1, to guard against drm client creation call multiple times. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amdgpu: dispositivo de zona de inicio y cliente drm después del restablecimiento del modo 1 al recargar. En el entorno de paso a través, cuando amdgpu se recarga después de la descarga, el modo 1 se activa después de inicializar las IP necesarias. • https://git.kernel.org/stable/c/4f8154f775197d0021b690c2945d6a4d8094c8f6 https://git.kernel.org/stable/c/f679fd6057fbf5ab34aaee28d58b7f81af0cbf48 •

https://notcve.org/view.php?id=CVE-2024-36021
In the Linux kernel, the following vulnerability has been resolved: net: hns3: fix kernel crash when devlink reload during pf initialization The devlink reload process will access the hardware resources, but the register operation is done before the hardware is initialized. So, processing the devlink reload during initialization may lead to kernel crash. This patch fixes this by taking devl_lock during initialization. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: hns3: soluciona el fallo del kernel cuando devlink se recarga durante la inicialización de pf. El proceso de recarga de devlink accederá a los recursos de hardware, pero la operación de registro se realiza antes de que se inicialice el hardware. Por lo tanto, procesar la recarga de devlink durante la inicialización puede provocar una falla del kernel. • https://git.kernel.org/stable/c/b741269b275953786832805df329851299ab4de7 https://git.kernel.org/stable/c/50b69054f455dcdb34bd6b22764c7579b270eef3 https://git.kernel.org/stable/c/1b550dae55901c2cc9075d6a7155a71b4f516e86 https://git.kernel.org/stable/c/7ca0f73e5e2da3c129935b97f3a0877cce8ebdf5 https://git.kernel.org/stable/c/93305b77ffcb042f1538ecc383505e87d95aa05a •
CVSS: 5.3EPSS: 0%CPEs: 9EXPL: 0CVE-2024-36020 – i40e: fix vf may be used uninitialized in this function warning
https://notcve.org/view.php?id=CVE-2024-36020
In the Linux kernel, the following vulnerability has been resolved: i40e: fix vf may be used uninitialized in this function warning To fix the regression introduced by commit 52424f974bc5, which causes servers hang in very hard to reproduce conditions with resets races. Using two sources for the information is the root cause. In this function before the fix bumping v didn't mean bumping vf pointer. But the code used this variables interchangeably, so stale vf could point to different/not intended vf. Remove redundant "v" variable and iterate via single VF pointer across whole function instead to guarantee VF pointer validity. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: i40e: se puede usar vf sin inicializar en esta función advertencia Para corregir la regresión introducida por el commit 52424f974bc5, que hace que los servidores se cuelguen con mucha dificultad para reproducir condiciones con restablecimientos de ejecución. El uso de dos fuentes para la información es la causa fundamental. En esta función, antes de la corrección, tocar v no significaba tocar el puntero vf. • https://git.kernel.org/stable/c/76ed715836c6994bac29d9638e9314e6e3b08651 https://git.kernel.org/stable/c/e88c2a1e28c5475065563d66c07ca879a9afbd07 https://git.kernel.org/stable/c/9abae363af5ced6adbf04c14366289540281fb26 https://git.kernel.org/stable/c/c39de3ae5075ea5f78e097cb5720d4e52d5caed9 https://git.kernel.org/stable/c/52424f974bc53c26ba3f00300a00e9de9afcd972 https://git.kernel.org/stable/c/02f949747e6fb767b29f7931d4bbf40911684e7a https://git.kernel.org/stable/c/cc9cd02dd9e8b7764ea9effb24f4f1dd73d1b23d https://git.kernel.org/stable/c/9dcf0fcb80f6aeb01469e3c957f8d4c97 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVSS: 6.1EPSS: 0%CPEs: 8EXPL: 0CVE-2024-36017 – rtnetlink: Correct nested IFLA_VF_VLAN_LIST attribute validation
https://notcve.org/view.php?id=CVE-2024-36017
In the Linux kernel, the following vulnerability has been resolved: rtnetlink: Correct nested IFLA_VF_VLAN_LIST attribute validation Each attribute inside a nested IFLA_VF_VLAN_LIST is assumed to be a struct ifla_vf_vlan_info so the size of such attribute needs to be at least of sizeof(struct ifla_vf_vlan_info) which is 14 bytes. The current size validation in do_setvfinfo is against NLA_HDRLEN (4 bytes) which is less than sizeof(struct ifla_vf_vlan_info) so this validation is not enough and a too small attribute might be cast to a struct ifla_vf_vlan_info, this might result in an out of bands read access when accessing the saved (casted) entry in ivvl. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: rtnetlink: Validación correcta del atributo IFLA_VF_VLAN_LIST anidado. Se supone que cada atributo dentro de un IFLA_VF_VLAN_LIST anidado es una estructura ifla_vf_vlan_info, por lo que el tamaño de dicho atributo debe ser al menos de sizeof(struct ifla_vf_vlan_info), que es de 14 bytes. La validación de tamaño actual en do_setvfinfo es contra NLA_HDRLEN (4 bytes), que es menor que sizeof(struct ifla_vf_vlan_info), por lo que esta validación no es suficiente y un atributo demasiado pequeño podría convertirse en una estructura ifla_vf_vlan_info, esto podría resultar en un acceso de lectura fuera de banda al acceder a la entrada guardada (transmitida) en ivvl. • https://git.kernel.org/stable/c/79aab093a0b5370d7fc4e99df75996f4744dc03f https://git.kernel.org/stable/c/8ac69ff2d0d5be9734c4402de932aa3dc8549c1a https://git.kernel.org/stable/c/5e7ef2d88666a0212db8c38e6703864b9ce70169 https://git.kernel.org/stable/c/6c8f44b02500c7d14b5e6618fe4ef9a0da47b3de https://git.kernel.org/stable/c/f3c1bf3054f96ddeab0621d920445bada769b40e https://git.kernel.org/stable/c/6e4c7193954f4faab92f6e8d88bc5565317b44e7 https://git.kernel.org/stable/c/206003c748b88890a910ef7142d18f77be57550b https://git.kernel.org/stable/c/4a4b9757789a1551d2df130df23bfb354 • CWE-125: Out-of-bounds Read •
