The latest Linux 6.18 kernel release includes crucial security hardening against malicious EROFS images that could trigger system failures. Security improvements target specially-crafted filesystem images that previously caused kernel panics. Meanwhile, the update brings significant enhancements to FUSE functionality for improved user-space filesystem operations.
Linux Kernel Security Hardening Against Malicious Filesystem Images
The Linux 6.18 kernel release includes important security hardening measures that protect systems against specially-crafted EROFS images capable of causing system crashes, according to reports from kernel development sources. The vulnerability, which has now been addressed, could previously allow malicious EROFS (Enhanced Read-Only File System) images to trigger kernel panics and system instability.
