CVE-2026-97610

A flaw was found in the Linux kernel's netfs network filesystem subsystem. A local user can cause a Denial of Service DoS or unexpected system behavior during synchronous unbuffered write operations on network filesystems, such as CIFS Common Internet File System. When an initial write preparatio...

CVE-2026-98120

A flaw was found in the Linux kernel's netfs network filesystem subsystem. A local user can cause a Denial of Service DoS by initiating specific unbuffered write operations on an affected filesystem. When a write subrequest encounters zero-length data during preparation, the kernel fails to relea...

CVE-2026-98119

A flaw was found in the Linux kernel's netfs network filesystem subsystem. A local user could cause a Denial of Service DoS by triggering a system crash when performing unbuffered write operations under memory exhaustion conditions. This issue occurs because the kernel fails to verify that memory...

CVE-2026-98118

A flaw was found in the Linux kernel's netfs network filesystem subsystem. A local user could exploit a race condition during readahead operations to cause a Denial of Service DoS via a system crash. This issue stems from improper synchronization between the application thread and collector threa...
