CVE-2024-50272
Published: November 21, 2024Last modified: November 21, 2024
Description
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.
