kernel: Linux kernel: Denial of Service in erofs filesystem

A flaw was found in the Linux kernel's erofs filesystem. A remote attacker can exploit this vulnerability without requiring any privileges. This issue occurs when insufficient memory during a memory mapping operation vmmapram in the bio completion path leads to a deadlock, causing a Denial of...

[SECURITY] Fedora 45 Update: erofs-utils-1.9.4-2.fc45

EROFS stands for Enhanced Read-Only File System. It aims to be a general read-only file system solution for various use cases instead of just focusing on saving storage space without considering runtime performance. This package includes tools to create, check, and extract EROFS images...

SUSE CVE-2026-98067

In the Linux kernel, the following vulnerability has been resolved: erofs: disable LZ4 rolling decompression for now LZ4 rolling decompression 1 was introduced to reduce the memory footprint of temporary pages: For many cases, it is needed for users to read small data within a compressed extent...

CVE-2026-98067

A flaw was found in the Linux kernel's EROFS Enhanced Read-Only File System. The rolling decompression mechanism used for LZ4-compressed files assumes that data is always copied forward in memory. On certain system architectures, the underlying memory copy operation can copy backward, invalidatin...

CVE-2026-98005

A flaw was found in the Linux kernel's EROFS Enhanced Read-Only File System component. Due to a missing delimiter between the domain identifier and fingerprint when generating cache keys for shared inodes, the resulting cache entries are ambiguous. A local user could exploit this ambiguity to cau...

CVE-2026-98067

The Linux kernel 's erofs filesystem was found to have a broken optimization where LZ4 rolling decompression could compromise data correctness. This occurred because the upstream LZ4 implementation might copy long literals backward on x86 systems, violating the rolling window assumption. To ensur...
