CVE-2026-92494

A flaw was found in the Linux kernel's ext4 filesystem. When handling orphan file blocks, the system may fail to properly release memory resources if block validation checks fail. This memory leak could lead to resource exhaustion over time, potentially resulting in a Denial of Service DoS for th...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ext4: Verify that the size of orphan files is not too large. In principle, orphan files can be arbitrarily large. However, orphan replay operations need to traverse those files, and all their buffers are stored in memory...

EUVD-2025-150395

In the Linux kernel, the following vulnerability has been resolved: ext4: verify orphan file size is not too big In principle orphan file can be arbitrarily large. However orphan replay needs to traverse it all and we also pin all its buffers in memory. Thus filesystems with absurdly large orphan...

CVE-2025-40179

CVE-2025-40179 concerns the Linux kernel’s ext4 filesystem. The issue arises from how orphan files are replayed: an orphan file can be arbitrarily large, and replay requires traversing it and pinning its buffers in memory, which can lead to excessive memory consumption on filesystems with very la...
