In the Linux kernel, the following vulnerability has been resolved: platform/x86/intel/pmt: fix a crashlog NULL pointer access Usage of the intel_pmt_read() for binary sysfs, requires a pcidev. The current use of the endpoint value is only valid for telemetry endpoint usage. Without the ep, the crashlog usage causes the following NULL pointer exception: BUG: kernel NULL pointer dereference, address: 0000000000000000 Oops: Oops: 0000 [#1] SMP NOPTI RIP: 0010:intel_pmt_read+0x3b/0x70 [pmt_class] Code: Call Trace: <TASK> ? sysfs_kf_bin_read+0xc0/0xe0 kernfs_fop_read_iter+0xac/0x1a0 vfs_read+0x26d/0x350 ksys_read+0x6b/0xe0 __x64_sys_read+0x1d/0x30 x64_sys_call+0x1bc8/0x1d70 do_syscall_64+0x6d/0x110 Augment struct intel_pmt_entry with a pointer to the pcidev to avoid the NULL pointer exception.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: platform/x86/intel/pmt: corrección de un acceso a puntero nulo en el registro de fallos. El uso de intel_pmt_read() para sistemas binarios sysfs requiere un pcidev. El uso actual del valor del endpoint solo es válido para el uso de endpoints de telemetría. Sin el ep, el uso del registro de fallos provoca la siguiente excepción de puntero nulo: ERROR: desreferencia de puntero nulo del kernel, dirección: 0000000000000000 ¡Uy!: ¡Uy!: 0000 [#1] SMP NOPTI RIP: 0010:intel_pmt_read+0x3b/0x70 [pmt_class] Código: Seguimiento de llamadas: ? Aumente la estructura intel_pmt_entry con un puntero a pcidev para evitar la excepción del puntero NULL.
