CVE-2026-80899

CVE-2026-80899 affects the Linux kernel's EROFS filesystem fscache backend . The fscache subsystem introduced a hard dependency on netfs for a local filesystem and imposed a kernel-defined caching hierarchy considered inflexible compared to fanotify pre-content hooks. The feature had been depreca...

EUVD-2026-71648

In the Linux kernel, the following vulnerability has been resolved: netfs: clear PGprivate2 on copy-to-cache append failure netfspgpriv2copytocache marks the folio with PGprivate2 before netfspgpriv2copyfolio appends it to the copy-to-cache rolling buffer. If the append fails, the folio is not...

CVE-2026-80898

CVE-2026-80898 affects the Linux kernel netfs subsystem. In netfs_pgpriv2_copy_to_cache(), a folio is marked with PG_private_2 before being appended to the copy-to-cache rolling buffer by netfs_pgpriv2_copy_folio(). If the append fails, the folio is not queued for cache writeback, yet the PG_priv...

EUVD-2026-71647

In the Linux kernel, the following vulnerability has been resolved: netfs: release readahead folios on iterator preparation failure netfspreparereaditerator batches readahead folios in putbatch so that the folio references can be dropped after the I/O iterator has been prepared. If...

CVE-2026-80897

In the Linux kernel, the following vulnerability has been resolved: netfs: release readahead folios on iterator preparation failure netfspreparereaditerator batches readahead folios in putbatch so that the folio references can be dropped after the I/O iterator has been prepared. If...

CVE-2026-80897 netfs: release readahead folios on iterator preparation failure

In the Linux kernel, the following vulnerability has been resolved: netfs: release readahead folios on iterator preparation failure netfspreparereaditerator batches readahead folios in putbatch so that the folio references can be dropped after the I/O iterator has been prepared. If...

CVE-2026-80897

CVE-2026-80897 affects the Linux kernel netfs subsystem. In netfs_prepare_read_iterator(), readahead folios are batched in put_batch so that references can be dropped after the I/O iterator is prepared. If rolling_buffer_load_from_ra() fails after earlier folios have been batched, the function re...

The vulnerability of the netfs_retry_read_subrequests() function in the fs/netfs/read_retry.c file of the Netfs file system in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the netfsretryreadsubrequests function in the fs/netfs/readretry.c file of the Netfs file system in the Linux operating system is related to the repeated use of previously released memory. Exploiting this vulnerability could allow a remote attacker to compromise the...

The vulnerability of the netfs_read_unlock_folios() function in the fs/netfs/read_collect.c module, which is part of the Linux kernel’s network file system support, allows a attacker to gain access to protected information or cause service interruptions.

The vulnerability of the netfsreadunlockfolios function in the fs/netfs/readcollect.c module, which is part of the Linux kernel’s network file system support, relates to the execution of operations outside the buffer boundaries. Exploiting this vulnerability could allow an attacker to access...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: netfs, fscache: This issue prevents Oops exceptions in fscacheputcache. This function dereferences the “cache” object, and then checks whether it is ISERRORNULL. It checks first, and then derefs the object...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: netfs: Only call foliostartfscache once for each folio. If a network filesystem using netfs implements a clamplength function, it can set subrequest lengths that are smaller than the page size. When we loop through the folios in...

CVE-2026-74542

A flaw was found in the netfs component of the Linux kernel. A memory allocation failure ENOMEM can occur during writeback operations when the system attempts to allocate folioqueue resources. This issue can lead to a kernel warning and potential system instability, which a local attacker could...

CVE-2026-72365

A flaw was found in the netfs component of the Linux kernel. This vulnerability arises from incorrect handling of NETFSRREQOFFLOADCOLLECTION during writethrough operations. This issue could lead to asynchronous OSYNC writes not being properly collected, potentially resulting in data inconsistency...

CVE-2026-72364

A flaw was found in the netfs component of the Linux kernel. This vulnerability arises from improper error handling in the writebackiter loop. When an error occurs during writeback operations, the system fails to correctly clean up iteration states and manage memory folios. This can lead to...

CVE-2026-72363

A flaw was found in the netfs component of the Linux kernel. This vulnerability occurs when the system runs out of memory during a data write operation, leading to an incorrect state for the affected memory pages folios. An attacker could potentially trigger this condition, which may cause the...

CVE-2026-72355

A flaw was found in the Linux kernel's netfs component. This vulnerability arises from incorrect barriering when processing the subrequest list, allowing a subrequest to be observed before it has been fully added by the application thread. This race condition could lead to unexpected system...
