CVE-2026-64059

A flaw was found in the Linux kernel's network filesystem netfs component. The netfsperformwrite function, responsible for handling write operations, does not correctly manage private data associated with memory pages, known as folios. This improper handling can lead to memory leaks, where system...

CVE-2026-64066

A flaw was found in the Linux kernel's netfs component. The netfsreadtopagecache function does not properly pause the generation of new subrequests when a previously issued subrequest has failed. This oversight can lead to continued resource consumption or incorrect system state, potentially...

CVE-2026-64060

A flaw was found in the netfs component of the Linux kernel. An issue in the error handling of the netfswritebegin function can lead to a leak of a request resource. This occurs when an error is returned from netfswaitforread, preventing the proper release of the resource. This resource leak may...

CVE-2026-64158

A flaw was found in the netfs component of the Linux kernel. The write streaming feature, which caches dirty data to avoid unnecessary reads, was incorrectly disabled when a file descriptor was opened with ORDWR read-write mode. This incorrect disabling was based on an outdated assumption that...

CVE-2026-64160

A flaw was found in the Linux kernel's network file system netfs component. This vulnerability, known as 'tearing', occurs when the system attempts to update file size information remoteisize and zeropoint without proper synchronization. This can lead to corrupted file size counters isizeseqcount...

CVE-2026-64068

A flaw was found in the Linux kernel's netfs component. This vulnerability arises from missing locking around the retry logic when adding new subrequests within the netfsretryreadsubrequests and netfsretrywritestream functions. An attacker could potentially exploit this race condition, which may...

CVE-2026-64063

A flaw was found in the Linux kernel's netfs component. This vulnerability occurs when the netfslib performs a 'streaming write' where dirty data is stored directly into folios without prior reading. If a partially written streaming write page is entirely or partially overwritten by a subsequent...

CVE-2026-64069
