Subject: Re: [Security] TIPC security issues Vulnerability: Another iovec overflow in networking, this time RDS Location: around line 490 Cause: - Data Type Issue: Uses for page count which can overflow when adding large numbers of pages. - Size Limit: Each iovec entry is limited to pages. - Page Count Overflow: Total pages can reach leading to potential overflow. Patch Details: - Fix: Check for negative before adding to prevent overflow. - Uncompiled: Linus notes the patch is untested. Additional Issues: - Potential race conditions with iovec changes in user space after page count is computed. - Other bugs may be present in the same subsystem. Recommendation: - Disable RDS in any sane setup due to unresolved issues.
