CVE-2025-39886
CVE-2025-39886 in the Linux kernel relates to a locking issue triggered when bpf_map_kmalloc_node() is called from __bpf_async_init(), potentially affecting memcg accounting and causing MEMCG_MAX events. The documented fix changes the bpf_timer_init() path to use allow_spinning=false and, per ups...

CVE-2025-38723
CVE-2025-38723 concerns the Linux kernel, specifically LoongArch BPF tailcall handling. The issue arises in the tailcall jump offset calculation when bpf_int_jit_compile() fails to initialize the JIT context, leaving out_offset = -1. Consequently, the computed jmp_offset = (out_offset - cur_offse...
