CVE-2024-35989

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Fix oops during rmmod on single-CPU platforms During the removal of the idxd driver, registered offline callback is invoked as part of the clean up process. However, on systems with only one CPU online, no valid target is available to migrate the perf context, resulting in a kernel oops: BUG: unable to handle page fault for address: 000000000002a2b8 #PF: supervisor write access in kernel mode #PF: error_code(0x0002) - not-present page PGD 1470e1067 P4D 0 Oops: 0002 [#1] PREEMPT SMP NOPTI CPU: 0 PID: 20 Comm: cpuhp/0 Not tainted 6.8.0-rc6-dsa+ #57 Hardware name: Intel Corporation AvenueCity/AvenueCity, BIOS BHSDCRB1.86B.2492.D03.2307181620 07/18/2023 RIP: 0010:mutex_lock+0x2e/0x50 ...

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: dmaengine: idxd: soluciona errores durante rmmod en plataformas de CPU única Durante la eliminación del controlador idxd, se invoca la devolución de llamada sin conexión registrada como parte del proceso de limpieza. Sin embargo, en sistemas con una sola CPU en línea, no hay ningún destino válido disponible para migrar el contexto de rendimiento, lo que genera un error del kernel: ERROR: no se puede manejar el error de página para la dirección: 000000000002a2b8 #PF: acceso de escritura del supervisor en modo kernel #PF: error_code(0x0002) - página no presente PGD 1470e1067 P4D 0 Ups: 0002 [#1] PREEMPT SMP NOPTI CPU: 0 PID: 20 Comm: cpuhp/0 No contaminado 6.8.0-rc6-dsa+ #57 Nombre de hardware: Intel Corporation AvenueCity/AvenueCity, BIOS BHSDCRB1.86B.2492.D03.2307181620 18/07/2023 RIP: 0010:mutex_lock+0x2e/0x50 ...
