https://notcve.org/view.php?id=CVE-2024-53114
In the Linux kernel, the following vulnerability has been resolved: x86/CPU/AMD: Clear virtualized VMLOAD/VMSAVE on Zen4 client A number of Zen4 client SoCs advertise the ability to use virtualized VMLOAD/VMSAVE, but using these instructions is reported to be a cause of a random host reboot. These instructions aren't intended to be advertised on Zen4 client so clear the capability. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: x86/CPU/AMD: Borrar VMLOAD/VMSAVE virtualizado en el cliente Zen4 Varios SoC de cliente Zen4 anuncian la capacidad de usar VMLOAD/VMSAVE virtualizado, pero se informa que el uso de estas instrucciones es la causa de un reinicio aleatorio del host. Estas instrucciones no están destinadas a ser anunciadas en el cliente Zen4, por lo que se debe borrar la capacidad. • https://git.kernel.org/stable/c/00c713f84f477a85e524f34aad8fbd11a1c051f0 https://git.kernel.org/stable/c/a5ca1dc46a6b610dd4627d8b633d6c84f9724ef0 •

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Adjust VSDB parser for replay feature At some point, the IEEE ID identification for the replay check in the AMD EDID was added. However, this check causes the following out-of-bounds issues when using KASAN: [ 27.804016] BUG: KASAN: slab-out-of-bounds in amdgpu_dm_update_freesync_caps+0xefa/0x17a0 [amdgpu] [ 27.804788] Read of size 1 at addr ffff8881647fdb00 by task systemd-udevd/383 ...

In the Linux kernel, the following vulnerability has been resolved: hv_sock: Initializing vsk->trans to NULL to prevent a dangling pointer When hvs is released, there is a possibility that vsk->trans may not be initialized to NULL, which could lead to a dangling pointer. This issue is resolved by initializing vsk->trans to NULL. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: hv_sock: inicialización de vsk->trans en NULL para evitar un puntero colgante. Cuando se lanza hvs, existe la posibilidad de que vsk->trans no se inicialice en NULL, lo que podría provocar un puntero colgante.
