Frag Gap (CVE-2026-53362, CVE-2026-53366)
TL;DR
A vulnerability in the Linux UDPv6 corking path allows an out-of-bounds write into skb_shared_info, potentially leading to memory corruption. This flaw can create a dangling pipe page, enabling unauthorized access to physical memory.
✦ Why It Matters
Review and patch affected Linux kernel versions to mitigate potential security risks from this vulnerability.
Key Takeaways
- Update Linux kernel to the latest version to patch vulnerabilities.
- Monitor systems for unusual behavior indicating potential exploitation.
- Review socket buffer handling code for similar vulnerabilities.
- Educate teams on secure coding practices to prevent memory corruption issues.
How It Works
The Fraggap vulnerability exploits a flaw in the UDP corking mechanism, where the kernel incorrectly handles the size of data being copied into socket buffers. This leads to an out-of-bounds write into the skb_shared_info structure, allowing an attacker to manipulate memory and gain control over kernel operations.
