CVE-2024-38604

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-38604
In the Linux kernel, the following vulnerability has been resolved: block: refine the EOF check in blkdev_iomap_begin blkdev_iomap_begin rounds down the offset to the logical block size before stashing it in iomap->offset and checking that it still is inside the inode size. Check the i_size check to the raw pos value so that we don't try a zero size write if iter->pos is unaligned.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: bloque: refina la comprobación de EOF en blkdev_iomap_begin blkdev_iomap_begin redondea hacia abajo el desplazamiento al tamaño del bloque lógico antes de guardarlo en iomap->offset y comprobar que todavía está dentro del tamaño del inodo. Verifique la verificación i_size en el valor pos sin formato para que no intentemos una escritura de tamaño cero si iter->pos no está alineado.
