  3. CVE-2022-49453
In the Linux kernel, the following vulnerability has been resolved: soc: ti: ti_sci_pm_domains: Check for null return of devm_kcalloc The allocation funciton devm_kcalloc may fail and return a null pointer, which would cause a null-pointer dereference later. It might be better to check it and directly return -ENOMEM just like the usage of devm_kcalloc in previous code.

CWE CWE-476
Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: soc: ti: ti_sci_pm_domains: Verificación de retorno nulo de devm_kcalloc La función de asignación devm_kcalloc puede fallar y devolver un puntero nulo, lo que provocaría una desreferencia de puntero nulo más adelante. Puede ser mejor verificarlo y devolver directamente -ENOMEM tal como se hizo con devm_kcalloc en el código anterior.
