In the Linux kernel, the following vulnerability has been resolved: igc: fix potential skb leak in igc_fpe_xmit_smd_frame() When… (CVE-2026-64110)
A vulnerability in the Linux kernel's igc driver caused a potential socket buffer (skb) memory leak in the function igc_fpe_xmit_smd_frame(). This occurred when igc_fpe_init_tx_descriptor() failed, and the allocated skb was not freed properly. The issue has been resolved by ensuring dev_kfree_skb_any() is called on failure to prevent the leak.
AI Analysis
Technical Summary
The Linux kernel igc driver contained a flaw where, upon failure of igc_fpe_init_tx_descriptor(), the allocated socket buffer (skb) was not freed, causing a memory leak. This was identified and fixed by adding a call to dev_kfree_skb_any() in the error path within igc_fpe_xmit_smd_frame(). The fix was tested on an I226 adapter with fault injection to confirm the resolution.
Potential Impact
The vulnerability leads to a potential memory leak in the kernel network driver, which could degrade system stability or performance over time due to unreleased memory. There is no indication of direct code execution or privilege escalation impact from the provided data.
Mitigation Recommendations
A fix has been implemented in the Linux kernel to address this issue by properly freeing the allocated skb on failure. Users should apply the official kernel updates that include this fix. Patch status is not explicitly confirmed in the provided data; check the vendor or Linux kernel advisories for the exact fixed versions and update accordingly.
