CVE-2025-68761: Linux

High severity, CVSS 7.8. EPSS: 0.1% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: hfs: fix potential use after free in hfs_correct_next_unused_CNID() This code calls hfs_bnode_put(node) which drops the refcount and then dreferences "node" on the next line. It's only safe to use "node" when we're holding a reference so flip these two lines around.

Affected products

• Linux Linux: from 6.18, before 6.18.2 (fixed in 6.18.2)
