CVE-2025-38113

In the Linux kernel, the following vulnerability has been resolved: ACPI: CPPC: Fix NULL pointer dereference when nosmp is used With nosmp in cmdline, other CPUs are not brought up, leaving their cpc_desc_ptr NULL. CPU0's iteration via for_each_possible_cpu() dereferences these NULL pointers, causing panic. Panic backtrace: [ 0.401123] Unable to handle kernel NULL pointer dereference at virtual address 00000000000000b8 ... [ 0.403255] [<ffffffff809a5818>] cppc_allow_fast_switch+0x6a/0xd4 ... Kernel panic - not syncing: Attempted to kill init! [ rjw: New subject ]

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ACPI: CPPC: Se corrige la desreferencia de punteros nulos al usar nosmp. Con nosmp en la línea de comandos, no se inician otras CPU, dejando su cpc_desc_ptr en NULL. La iteración de la CPU0 mediante for_each_possible_cpu() desreferencia estos punteros nulos, lo que provoca pánico. Seguimiento de pánico: [0.401123] No se puede gestionar la desreferencia de punteros nulos del kernel en la dirección virtual 0000000000000b8 ... [0.403255] [] cppc_allow_fast_switch+0x6a/0xd4 ... Pánico del kernel: no se sincroniza: ¡Se intentó detener la inicialización! [rjw: Nuevo asunto]
