  3. CVE-2022-48703
In the Linux kernel, the following vulnerability has been resolved: thermal/int340x_thermal: handle data_vault when the value is ZERO_SIZE_PTR In some case, the GDDV returns a package with a buffer which has zero length. It causes that kmemdup() returns ZERO_SIZE_PTR (0x10). Then the data_vault_read() got NULL point dereference problem when accessing the 0x10 value in data_vault. [ 71.024560] BUG: kernel NULL pointer dereference, address: 0000000000000010 This patch uses ZERO_OR_NULL_PTR() for checking ZERO_SIZE_PTR or NULL value in data_vault.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Thermal/int340x_thermal: maneja data_vault cuando el valor es ZERO_SIZE_PTR. En algunos casos, el GDDV devuelve un paquete con un buffer que tiene longitud cero. Provoca que kmemdup() devuelva ZERO_SIZE_PTR (0x10). Luego, data_vault_read() tuvo un problema de desreferencia de punto NULL al acceder al valor 0x10 en data_vault. [71.024560] ERROR: desreferencia del puntero NULL del kernel, dirección: 00000000000000010 Este parche usa ZERO_OR_NULL_PTR() para verificar ZERO_SIZE_PTR o el valor NULL en data_vault.
