  3. CVE-2022-49262
In the Linux kernel, the following vulnerability has been resolved: crypto: octeontx2 - remove CONFIG_DM_CRYPT check No issues were found while using the driver with dm-crypt enabled. So CONFIG_DM_CRYPT check in the driver can be removed. This also fixes the NULL pointer dereference in driver release if CONFIG_DM_CRYPT is enabled. ... Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008 ...

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: crypto: octeontx2 - eliminar la comprobación CONFIG_DM_CRYPT No se encontraron problemas al usar el controlador con dm-crypt habilitado. Por lo tanto, se puede eliminar la comprobación CONFIG_DM_CRYPT en el controlador. Esto también corrige la desreferencia del puntero NULL en la versión del controlador si CONFIG_DM_CRYPT está habilitado. ... No se puede manejar la desreferencia del puntero NULL del kernel en la dirección virtual 0000000000000008 ...
