CVE-2026-97552

A flaw was found in the Linux kernel's XFS file system. An uninitialized variable in the deferred operation handling routine can cause the kernel to return an indeterminate value when processing empty work items during online repair. A local user initiating or interacting with file system repair...

CVE-2026-97549

A flaw was found in the Linux kernel's XFS file system. An incorrect block calculation during the online repair of shortform directories and extended attributes causes transaction space to be under-reserved. A local user capable of triggering metadata repair operations can exploit this flaw to...

CVE-2026-97546

A flaw was found in the Linux kernel's XFS file system. A local user could trigger this vulnerability by mounting or repairing a corrupted file system containing zero-length directory entries. When salvaging these malformed entries during directory repair operations, the kernel fails to advance a...

CVE-2026-97544

A flaw was found in the Linux kernel's XFS file system. This flaw allows a local user to cause a Denial of Service DoS through kernel memory exhaustion. The issue occurs during live quota check operations when memory allocated for quota tracking is not freed if an internal hash table insertion...

CVE-2026-97542

A flaw was found in the Linux kernel's XFS file system. When performing online repair of an allocation group free list AGFL, the kernel fails to check return values during bitmap processing, silently ignoring errors. A local user capable of triggering file system repair operations could cause the...

CVE-2026-97545

A flaw was found in the Linux kernel's XFS file system. When an input/output I/O error occurs while writing cached data buffers to disk during b-tree preparation, the kernel fails to release an allocated buffer. A local user performing file system operations could trigger this condition to leak...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mm, thp: Bail out early for writeback pages in collapsefile Currently, collapsefile does not explicitly check PGwriteback. Instead, pagehasprivate and trytoreleasepage are used to filter writeback pages. This approach does not wo...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A vulnerability related to out-of-bounds memory access was discovered in the Linux kernel’s XFS file system, regarding how a user restores an XFS image after a failure with a dirty log journal. This vulnerability allows a local user to crash the system or potentially escalate their privileges on...

kernel: XFS data corruption using reflink

A flaw was found in the XFS filesystem. A race condition in the copy-on-write mechanism for reflinked files can cause writes to bypass the copy-on-write process and modify shared data blocks directly. As a result, data intended for a private copy may be written to the original shared location,...

EUVD-2026-48901

In the Linux kernel, the following vulnerability has been resolved: xfs: fix exchmaps reservation limit check xfsexchmapsestimateoverhead adds the bmbt and rmapbt overhead to a local resblks variable, but the final UINTMAX check still tests req-resblks. That is the reservation value from before t...

CVE-2026-64357

In the Linux kernel, the following vulnerability has been resolved: xfs: fix exchmaps reservation limit check xfsexchmapsestimateoverhead adds the bmbt and rmapbt overhead to a local resblks variable, but the final UINTMAX check still tests req-resblks. That is the reservation value from before t...

CVE-2026-64357

CVE-2026-64357 affects the Linux kernel's XFS filesystem . The bug is in xfs_exchmaps_estimate_overhead(), which adds bmbt and rmapbt overhead to a local resblks variable, but the final UINT_MAX limit check still tests req->resblks—the pre-overhead value. The computed (post-overhead) value is ...

EUVD-2026-48900

In the Linux kernel, the following vulnerability has been resolved: xfs: fix memory leak in xfsdqinodemetadircreate If xfsmetadircreate fails in xfsdqinodemetadircreate, the current code returns directly, leaking the allocated update and transaction state. If the subsequent commit fails, the...

CVE-2026-64600 xfs: resample the data fork mapping after cycling ILOCK

In the Linux kernel, the following vulnerability has been resolved: xfs: resample the data fork mapping after cycling ILOCK xfsreflinkfillcowhole,delalloc are both presented with an inode, a data fork mapping, and a cow fork mapping. Unfortunately, these two helpers cycle the ILOCK to grab a...

CVE-2026-64187

A flaw was found in the Linux kernel's XFS filesystem log recovery component. A local attacker could exploit this vulnerability by crafting a malicious XFS log. When the system attempts to recover from this log, it triggers a null-pointer dereference, which can lead to a system crash. This result...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: xfs: removed xfsattrleafhasname The calling convention of xfsattrleafhasname is problematic because it returns a NULL buffer when xfsattr3leafread fails, a valid buffer when xfsattr3leaflookupint returns -ENOATTR or -EEXIST, and ...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: xfs: Only call xfarray,blobdestroy if we have a valid pointer. Only call the xfarray and xfblob destructors if we have a valid pointer, and make sure to null out that pointer afterwards. Note that this patch fixes a large number ...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: xfs: Check for deleted cursors when revalidating two btrees. The free space and inode btree repair functions will rebuild both btrees at the same time. After that, it is necessary to evaluate both btrees to confirm that the...

kernel: xfs: fix freemap adjustments when adding xattrs to leaf blocks

A flaw was found in the Linux kernel's XFS filesystem. When adding extended attributes xattrs, which are metadata associated with files, to leaf blocks, incorrect adjustments to the freemap can occur. This inconsistency allows the entries array and free space to overlap, leading to an assertion...
