https://notcve.org/view.php?id=CVE-2024-26772
In the Linux kernel, the following vulnerability has been resolved: ext4: avoid allocating blocks from corrupted group in ext4_mb_find_by_goal() Places the logic for checking if the group's block bitmap is corrupt under the protection of the group lock to avoid allocating blocks from the group with a corrupted block bitmap. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ext4: evita asignar bloques del grupo corrupto en ext4_mb_find_by_goal() Coloca la lógica para verificar si el mapa de bits del bloque del grupo está corrupto bajo la protección del bloqueo del grupo para evitar la asignación de bloques del grupo con un mapa de bits de bloque dañado. A vulnerability was found in the ext4_mb_find_by_goal() function in the Linux kernel. This issue could lead to memory corruption or crashes due to the allocation of blocks from a group with a corrupted block bitmap. • https://git.kernel.org/stable/c/5a6dcc4ad0f7f7fa8e8d127b5526e7c5f2d38a43 https://git.kernel.org/stable/c/6b92b1bc16d691c95b152c6dbf027ad64315668d https://git.kernel.org/stable/c/ffeb72a80a82aba59a6774b0611f792e0ed3b0b7 https://git.kernel.org/stable/c/8de8305a25bfda607fc13475ebe84b978c96d7ff https://git.kernel.org/stable/c/d639102f4cbd4cb65d1225dba3b9265596aab586 https://git.kernel.org/stable/c/d3bbe77a76bc52e9d4d0a120f1509be36e25c916 https://git.kernel.org/stable/c/21dbe20589c7f48e9c5d336ce6402bcebfa6d76a https://git.kernel.org/stable/c/832698373a25950942c04a512daa652c1 • CWE-229: Improper Handling of Values •

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.
