CVE-2026-98844

A flaw was found in the Linux kernel's network filesystem netfs subsystem. When a file is extended through write operations after previous writes were performed via memory mapping, the system fails to clear stale cache data located beyond the original end of the file. A local user could exploit...

CVE-2026-98843

A flaw was found in the Linux kernel's Network Filesystem netfs subsystem. When reading data gaps around modified memory regions during streaming write operations, truncated or incomplete read responses from a remote server fail to clear unread memory buffers. As a result, stale memory contents c...

kernel: netfs: Fix early put of sink folio in netfs_read_gaps()

A flaw was found in the Linux kernel's network file system netfs. This use-after-free vulnerability occurs when the netfsreadgaps function prematurely releases a memory page during network read operations. A remote attacker could exploit this by sending specially crafted network traffic, leading ...

CVE-2026-98920

The Linux kernel contains a vulnerability where direct mempool allocations for folio_queues skipped the alloc_hooks() wrapper. This caused missing alloc tagging when CONFIG_MEM_ALLOC_PROFILING_DEBUG=y is enabled, resulting in kernel warnings during file reads on a CIFS mount and missing data in /...
