Summary

In the Linux kernel's batman-adv module, the function batadv_frag_send_packet() does not properly handle errors during pre-checks for empty payload or zero fragment size. In such cases, the skb is not freed, leading to memory leaks.

Risk Assessment

The vulnerability could lead to kernel memory leaks, potentially causing system crash or performance degradation.

Recommendation

Apply the Linux kernel patch that ensures proper skb freeing on error paths. Regularly monitor system memory usage.

Original NVD description (English source)

In the Linux kernel, the following vulnerability has been resolved: batman-adv: frag: free unfragmentable packet The caller of batadv_frag_send_packet() assume that the skb provided to the function are always consumed. But the pre-check for an empty payload or the zero fragment size returned an error without any further actions. A failed pre-check must use the same error handling code as the rest of the function.
