CVE-2024-50272
filemap: Fix bounds checking in filemap_read()
Résumé
filemap: Fix bounds checking in filemap_read()
Description d'origine
La description telle que publiée par la source (souvent en anglais).
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.
