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 •
CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-53113 – mm: fix NULL pointer dereference in alloc_pages_bulk_noprof
https://notcve.org/view.php?id=CVE-2024-53113
In the Linux kernel, the following vulnerability has been resolved: mm: fix NULL pointer dereference in alloc_pages_bulk_noprof We triggered a NULL pointer dereference for ac.preferred_zoneref->zone in alloc_pages_bulk_noprof() when the task is migrated between cpusets. When cpuset is enabled, in prepare_alloc_pages(), ac->nodemask may be ¤t->mems_allowed. when first_zones_zonelist() is called to find preferred_zoneref, the ac->nodemask may be modified concurrently if the task is migrated between different cpusets. Assuming we have 2 NUMA Node, when traversing Node1 in ac->zonelist, the nodemask is 2, and when traversing Node2 in ac->zonelist, the nodemask is 1. As a result, the ac->preferred_zoneref points to NULL zone. In alloc_pages_bulk_noprof(), for_each_zone_zonelist_nodemask() finds a allowable zone and calls zonelist_node_idx(ac.preferred_zoneref), leading to NULL pointer dereference. __alloc_pages_noprof() fixes this issue by checking NULL pointer in commit ea57485af8f4 ("mm, page_alloc: fix check for NULL preferred_zone") and commit df76cee6bbeb ("mm, page_alloc: remove redundant checks from alloc fastpath"). To fix it, check NULL pointer for preferred_zoneref->zone. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mm: corregir la desreferencia de puntero NULL en alloc_pages_bulk_noprof Activamos una desreferencia de puntero NULL para ac.preferred_zoneref->zone en alloc_pages_bulk_noprof() cuando la tarea se migra entre conjuntos de CPU. • https://git.kernel.org/stable/c/387ba26fb1cb9be9e35dc14a6d97188e916eda05 https://git.kernel.org/stable/c/6addb2d9501ec866d7b3a3b4e665307c437e9be2 https://git.kernel.org/stable/c/d0f16cec79774c3132df006cf771eddd89d08f58 https://git.kernel.org/stable/c/31502374627ba9ec3e710dbd0bb00457cc6d2c19 https://git.kernel.org/stable/c/8ce41b0f9d77cca074df25afd39b86e2ee3aa68e •

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.
