CVE-2022-49553

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2022-49553
In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: validate BOOT sectors_per_clusters When the NTFS BOOT sectors_per_clusters field is > 0x80, it represents a shift value. Make sure that the shift value is not too large before using it (NTFS max cluster size is 2MB). Return -EVINVAL if it too large. This prevents negative shift values and shift values that are larger than the field size. Prevents this UBSAN error: UBSAN: shift-out-of-bounds in ../fs/ntfs3/super.c:673:16 shift exponent -192 is negative

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: fs/ntfs3: validar sectores_por_clústeres de BOOT Cuando el campo sectores_por_clústeres de BOOT de NTFS es > 0x80, representa un valor de desplazamiento. Asegúrese de que el valor de desplazamiento no sea demasiado grande antes de usarlo (el tamaño máximo del clúster de NTFS es 2 MB). Devuelva -EVINVAL si es demasiado grande. Esto evita valores de desplazamiento negativos y valores de desplazamiento que sean más grandes que el tamaño del campo. Previene este error de UBSAN: UBSAN: desplazamiento fuera de los límites en ../fs/ntfs3/super.c:673:16 el exponente de desplazamiento -192 es negativo
