CVE-2026-98058

The Linux kernel contains a vulnerability where the bpf_sys_bpf() and bpf_sys_close() helpers lack the .might_sleep attribute. Because these helpers can take mutexes, allocate memory with GFP_KERNEL, or wait for RCU grace periods, their use in non-sleepable contexts—such as a bpf_timer callback e...
