CVE-2024-50272 is a medium severity vulnerability in the Linux kernel's filemap_read() function. It involves improper bounds checking when the caller provides an iocb->ki_pos value near the filesystem upper limit combined with an iterator count that causes an overflow. This flaw can cause filemap_read() to enter an infinite loop, potentially leading to denial of service. The issue was identified during testing with xfstests generic/525 using the "localio" optimization for loopback NFS mounts.
