Description
In the Linux kernel, the following vulnerability has been resolved:
octeon_ep_vf: add NULL check for napi_build_skb()
napi_build_skb() can return NULL on allocation failure. In
__octep_vf_oq_process_rx(), the result is used directly without a NULL
check in both the single-buffer and multi-fragment paths, leading to a
NULL pointer dereference.
Add NULL checks after both napi_build_skb() calls, properly advancing
descriptors and consuming remaining fragments on failure.
Affected configurations
• linux linux kernel (>= 6.9 < 6.12.88)
• linux linux kernel (>= 6.13 < 6.18.30)
• linux linux kernel (>= 6.19 < 7.0.7)
