CVE-2024-50272

  3. CVE-2024-50272
In the Linux kernel, the following vulnerability has been resolved: filemap: Fix bounds checking in filemap_read() If the caller supplies an iocb->ki_pos value that is close to the filesystem upper limit, and an iterator with a count that causes us to overflow that limit, then filemap_read() enters an infinite loop. This behaviour was discovered when testing xfstests generic/525 with the "localio" optimisation for loopback NFS mounts.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: filemap: Se ha corregido la comprobación de los límites en filemap_read() Si el llamador proporciona un valor iocb->ki_pos que está cerca del límite superior del sistema de archivos y un iterador con un recuento que hace que desbordemos ese límite, filemap_read() entra en un bucle infinito. Este comportamiento se descubrió al probar xfstests generic/525 con la optimización "localio" para montajes NFS de bucle invertido.
