GHSA-CH98-87FR-X9F7

Vulnerability from github – Published: 2024-11-19 03:31 – Updated: 2025-11-04 00:32

Details

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.

Severity ?

5.5 (Medium)
