Title: kernel de Linux
Description: En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: pstore: ram_core: corrige posible desbordamiento en persistent_ram_init_ecc() En persistent_ram_init_ecc(), en arcos de 64 bits DIV_ROUND_UP() devolverá un valor de 64 bits ya que persistent_ram_zone::buffer_size tiene el tipo size_t que se deriva del *unsigned long* de 64 bits, mientras que la variable ecc_blocks a la que se asigna este valor tiene (siempre 32 bits) el tipo *int*. Incluso si ese valor encaja en el tipo *int*, aún es posible un desbordamiento al calcular la variable ecc_total escrita size_t más abajo, ya que no hay conversión a ningún tipo de 64 bits antes de la multiplicación. Declarar la variable ecc_blocks como *size_t* debería solucionar este problema... Encontrado por el Centro de verificación de Linux (linuxtesting.org) con la herramienta de análisis estático SVACE.

Description
In the Linux kernel, the following vulnerability has been resolved:
pstore: ram_core: fix possible overflow in persistent_ram_init_ecc()
In persistent_ram_init_ecc(), on 64-bit arches DIV_ROUND_UP() will return
64-bit value since persistent_ram_zone::buffer_size has type size_t which
is derived from the 64-bit *unsigned long*, while the ecc_blocks variable
this value gets assigned to has (always 32-bit) *int* type. Even if that
value fits into *int* type, an overflow is still possible when calculating
the size_t typed ecc_total variable further below since there's no cast to
any 64-bit type before multiplication. Declaring the ecc_blocks variable
as *size_t* should fix this mess...
Found by Linux Verification Center (linuxtesting.org) with the SVACE static
analysis tool.
Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
