In the Linux kernel, the following vulnerability has been resolved: fuse: fix io-uring list corruption for terminated non-committed requests When a request is terminated before it has been committed, the request is not removed from the queue's list. This leaves a dangling list entry that leads to list corruption and use-after-free issues. Remove the request from the queue's list for terminated non-committed requests.
AI Analysis
Technical Summary
CVE-2025-68805 addresses a flaw in the Linux kernel's FUSE implementation related to io-uring request handling. Specifically, when a request is terminated before commitment, it remains in the queue's list, causing dangling list entries that lead to list corruption and use-after-free vulnerabilities. The fix removes these terminated non-committed requests from the queue to prevent such memory corruption issues.
Potential Impact
The vulnerability can cause list corruption and use-after-free conditions in the kernel, potentially allowing attackers with local privileges to compromise system confidentiality, integrity, and availability. The CVSS vector indicates local attack vector, low complexity, low privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
A fix has been implemented in the Linux kernel to remove terminated non-committed requests from the queue's list, resolving the issue. Users should apply the official kernel updates that include this patch once available. Patch status is not explicitly confirmed in the provided data; therefore, check the vendor advisory for current remediation guidance.
