Title: kernel de Linux
Description: En el kernel de Linux, se resolvió la siguiente vulnerabilidad: powerpc/ps3_defconfig: deshabilitar PPC64_BIG_ENDIAN_ELF_ABI_V2 Commit 8c5fa3b5c4df ("powerpc/64: hacer que ELFv2 sea el predeterminado para compilaciones big-endian"), combinado en Linux-6.5-rc1 cambia la ABI de llamada en de una manera que es incompatible con el código actual para las llamadas al hipervisor LV1 de la PS3. Este cambio simplemente agrega la línea '# CONFIG_PPC64_BIG_ENDIAN_ELF_ABI_V2 no está configurado' al archivo ps3_defconfig para que se use PPC64_ELF_ABI_V1. Corrige errores de tiempo de ejecución como estos: ERROR: Desreferencia del puntero NULL del kernel en 0x00000000 Dirección de instrucción errónea: 0xc000000000047cf0 Ups: Acceso al kernel del área defectuosa, firma: 11 [#1] Seguimiento de llamadas: [c0000000023039e0] [c00000000100ebfc] pu+0xc4/0x2b0 ( no confiable) [c000000002303ab0] [c00000000100d4c4] create_spu+0xcc/0x3c4 [c000000002303b40] [c00000000100eae4] ps3_enumerate_spus+0xa4/0xf8

In the Linux kernel, the following vulnerability has been resolved:

powerpc/ps3_defconfig: Disable PPC64_BIG_ENDIAN_ELF_ABI_V2

Commit 8c5fa3b5c4df ("powerpc/64: Make ELFv2 the default for big-endian
builds"), merged in Linux-6.5-rc1 changes the calling ABI in a way
that is incompatible with the current code for the PS3's LV1 hypervisor
calls.

This change just adds the line '# CONFIG_PPC64_BIG_ENDIAN_ELF_ABI_V2 is not set'
to the ps3_defconfig file so that the PPC64_ELF_ABI_V1 is used.

Fixes run time errors like these:

  BUG: Kernel NULL pointer dereference at 0x00000000
  Faulting instruction address: 0xc000000000047cf0
  Oops: Kernel access of bad area, sig: 11 [#1]
