In the Linux kernel, the following vulnerability has been resolved: ext4: clear stale xarray tags on folios skipped during writeback In data=journal mode, the writeback thread can hit the WARNONONCEsbrdonlysb in ext4journalcheckstart while the superblock is being remounted read-only during reboot...

CVE-2026-92502

CVE-2026-92502 affects the ext4 filesystem in the Linux kernel when using data=journal mode. The root cause is that folio_clear_dirty_for_io clears the PG_dirty flag but leaves the PAGECACHE_TAG_DIRTY and PAGECACHE_TAG_TOWRITE xarray tags set. In data=journal mode, jbd2 checkpoints journalled dat...

In the Linux kernel, the following vulnerability has been resolved: ext4: clear stale xarray tags on folios skipped during writeback In data=journal mode, the writeback thread can hit the WARNONONCEsbrdonlysb in ext4journalcheckstart while the superblock is being remounted read-only during reboot...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: jbd2: fixed the potential buffer head reference count leak. In the case of jbd2fcwaitbufs, if the buffer is not up-to-date, it will return -EIO without updating journal-jfcoff. However, in jbd2fcreleasebufs, the buffer head will ...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: gfs2: No more self-recovery. When a node withdraws from the system and it turns out that it is the only node with the filesystem mounted, gfs2 currently attempts to replay the local journal to restore the filesystem to a consiste...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ext4: Filter out the EXT4FCREPLAY bit from the on-disk superblock’s sstate field. The EXT4FCREPLAY bit in sbi-smountstate is used to indicate that we are currently replaying the fast commit journal. This was actually a mistake, a...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: jbd2: Stop waiting for space when jbd2cleanupjournaltail returns an error. In jbd2logwaitforspace, we may call jbd2cleanupjournaltail to reclaim some journal space. However, if an error occurs during the execution of...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: jbd2: removed the incorrect sb-ssequence check. The emptiness of the journal is determined not by sb-ssequence == 0, but rather by sb-sstart == 0 which is set a few lines above. Moreover, 0 is a valid transaction ID, so the check...

Astra Linux – Vulnerability in freeipa

A flaw was identified in the FreeIPA API audit; it sends the entire FreeIPA command line to journalctl. As a result, during the FreeIPA installation process, administrative user credentials—including the administrator’s password—are inadvertently leaked into the journal database. In the worst-cas...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ext4: Update sjournalinum if it changes after journal replay. When mounting a custom-extracted ext4 image, sjournalinum may change after journal replay. This is clearly unreasonable, as we have successfully loaded and replayed th...

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...

Astra Linux – Vulnerability in Linux 5.15

A use-after-free flaw was discovered in the Linux kernel, specifically in the logreplay function within fs/ntfs3/fslog.c in the NTFS journal. This flaw allows a local attacker to crash the system and causes a kernel information leak...

Linux Kernel NTFS3 Journal Heap-based Buffer Overflow Code Execution Vulnerability

This vulnerability allows local attackers to execute arbitrary code on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the processing of...

CVE-2026-89566 jbd2: check need_resched() when skipping busy checkpoint buffers

In the Linux kernel, the following vulnerability has been resolved: jbd2: check needresched when skipping busy checkpoint buffers journalshrinkonecplist skips busy checkpoint buffers when called with JBD2SHRINKBUSYSKIP. The continue statement on this path also skips the needresched check at the e...

PT-2026-96392

In the Linux kernel, the following vulnerability has been resolved: jbd2: bound shrinker scans by examined checkpoint buffers The jbd2 shrinker currently accounts only checkpoint buffers that it successfully releases against nr to scan. Busy buffers therefore do not consume the scan budget. If a...
