In the Linux kernel, the following vulnerabilities have been resolved: netfs: Fixed error handling for unbuffered writes If all subrequests in an unbuffered write stream fail, the subrequest collector does not update the stream-transferred value, and it retains its initial LONGMAX value...

SUSE CVE-2026-31437

In the Linux kernel, the following vulnerability has been resolved: netfs: Fix NULL pointer dereference in netfsunbufferedwrite on retry When a write subrequest is marked NETFSSREQNEEDRETRY, the retry path in netfsunbufferedwrite unconditionally calls stream-preparewrite without checking if it is...

CVE-2026-31437

A flaw was found in the Linux kernel's netfs component. When a write operation is retried, the netfsunbufferedwrite function can attempt to access a non-existent function, leading to a NULL pointer dereference. This vulnerability can be triggered by specific filesystem configurations, such as 9P,...

CVE-2026-31437

The CVE-2026-31437 issue is in the Linux kernel netfs path: when a write subrequest is marked NETFS_SREQ_NEED_RETRY, netfs_unbuffered_write() could dereference stream->prepare_write if it is NULL (not all filesystems, e.g., 9P, set prepare_write). The fixed behavior mirrors write_retry.c: if s...

CVE-2025-39723

CVE-2025-39723 affects the Linux kernel netfs unbuffered write path. When all subrequests in an unbuffered write stream fail, stream->transferred could remain LONG_MAX, and wreq->transferred could be updated to that value, causing write_iter() to report an erroneous non‑zero transfer and tr...
