CVE-2026-80986
CVE-2026-80986 affects the Linux kernel's SMC-Rv2 (Shared Memory Communications over RDMA v2) network subsystem. The flaw is in smc_llc_save_add_link_rkeys() : when a link's device has max_recv_sge == 1 , the v2 extension is read from offset 68 of a 72-byte slab allocation, so ext->num_rkeys a...
