CVE-2024-26853
A flaw in the Linux kernel’s XDP_REDIRECT handling can corrupt memory and crash the system. It occurs when a network frame cannot be transmitted and is mistakenly freed twice. The result is a kernel panic that can be triggered by sending heavy traffic through an Intel i225 NIC.
An official fix is available, so this entry is kept for 30 days and then removed automatically.
Who is affected
Linux kernel 6.8 and earlier, especially systems using Intel i225 network adapters and XDP_REDIRECT programs. Any user running a kernel that has not been patched for CVE-2024-26853 is at risk.
Real-world impact
An attacker can send crafted traffic that forces the kernel to crash, causing a denial‑of‑service. The crash can be triggered remotely over the network without any authentication.
Why this severity
The CVSS score of 9.8 reflects that the vulnerability is exploitable from the network, requires no privileges, and compromises confidentiality, integrity, and availability. The lack of authentication and the high impact of a kernel panic make it critical.
What to do about it
- 01Upgrade the Linux kernel to a version that includes the CVE‑2024‑26853 fix. The patch is incorporated in the latest stable kernel releases. After upgrading, reboot the system to load the new kernel.
