CVE-2022-48804

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2022-48804
In the Linux kernel, the following vulnerability has been resolved: vt_ioctl: fix array_index_nospec in vt_setactivate array_index_nospec ensures that an out-of-bounds value is set to zero on the transient path. Decreasing the value by one afterwards causes a transient integer underflow. vsa.console should be decreased first and then sanitized with array_index_nospec.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: vt_ioctl: corrige array_index_nospec en vt_setactivate array_index_nospec garantiza que un valor fuera de los límites se establezca en cero en la ruta transitoria. Disminuir el valor en uno posteriormente provoca un desbordamiento de enteros transitorio. vsa.console debe reducirse primero y luego desinfectarse con array_index_nospec.
