CVE-2026-43244

CVE-2026-43244 affects the Linux kernel KCM (Kernel Connection Multiplexer). The issue arises during partial sendmsg operations: when kcm_sendmsg fills MAX_SKB_FRAGS, it allocates a new skb in frag_list and may copy data; if the copy fails, the new tail skb can have zero frags, leaving an empty e...
