https://notcve.org/view.php?id=CVE-2024-26770
In the Linux kernel, the following vulnerability has been resolved: HID: nvidia-shield: Add missing null pointer checks to LED initialization devm_kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure. Ensure the allocation was successful by checking the pointer validity. [jkosina@suse.com: tweak changelog a bit] En el kernel de Linux, se resolvió la siguiente vulnerabilidad: HID: nvidia-shield: agregar comprobaciones de puntero nulo faltantes a la inicialización del LED devm_kasprintf() devuelve un puntero a la memoria asignada dinámicamente que puede ser NULL en caso de falla. Asegúrese de que la asignación se haya realizado correctamente comprobando la validez del puntero.

In the Linux kernel, the following vulnerability has been resolved: nvmet-fc: avoid deadlock on delete association path When deleting an association the shutdown path is deadlocking because we try to flush the nvmet_wq nested. Avoid this by deadlock by deferring the put work into its own work item. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nvmet-fc: evita el punto muerto al eliminar la ruta de asociación Al eliminar una asociación, la ruta de cierre se bloquea porque intentamos vaciar el nvmet_wq anidado.

CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2024-26768 – LoongArch: Change acpi_core_pic[NR_CPUS] to acpi_core_pic[MAX_CORE_PIC]
https://notcve.org/view.php?id=CVE-2024-26768
In the Linux kernel, the following vulnerability has been resolved: LoongArch: Change acpi_core_pic[NR_CPUS] to acpi_core_pic[MAX_CORE_PIC] With default config, the value of NR_CPUS is 64. When HW platform has more then 64 cpus, system will crash on these platforms. MAX_CORE_PIC is the maximum cpu number in MADT table (max physical number) which can exceed the supported maximum cpu number (NR_CPUS, max logical number), but kernel should not crash. Kernel should boot cpus with NR_CPUS, let the remainder cpus stay in BIOS. The potential crash reason is that the array acpi_core_pic[NR_CPUS] can be overflowed when parsing MADT table, and it is obvious that CORE_PIC should be corresponding to physical core rather than logical core, so it is better to define the array as acpi_core_pic[MAX_CORE_PIC]. With the patch, system can boot up 64 vcpus with qemu parameter -smp 128, otherwise system will crash with the following message.

This results in a panic when the send completion runs. The exact panic varies depending on what elements of the container structure get corrupted. The fix is to use the correct expression in _pad_sdma_tx_descs() to test the need to expand the descriptor array. With this patch the crashes are no longer reproducible and the machine is stable. • https://git.kernel.org/stable/c/d1c1ee052d25ca23735eea912f843bc7834781b4 https://git.kernel.org/stable/c/40ac5cb6cbb01afa40881f78b4d2f559fb7065c4 https://git.kernel.org/stable/c/6cf8f3d690bb5ad31ef0f41a6206ecf5a068d179 https://git.kernel.org/stable/c/bd57756a7e43c7127d0eca1fc5868e705fd0f7ba https://git.kernel.org/stable/c/eeaf35f4e3b360162081de5e744cf32d6d1b0091 https://git.kernel.org/stable/c/fd8958efe8779d3db19c9124fce593ce681ac709 https://git.kernel.org/stable/c/0ef9594936d1f078e8599a1cf683b052df2bec00 https://git.kernel.org/stable/c/115b7f3bc1dce590a6851a2dcf23dc110 •
