EUVD-2026-86711

In the Linux kernel, the following vulnerability has been resolved: bpf: Mark syscall helpers as sleepable bpfsysbpf executes the bpf2 syscall body, which can take mutexes, allocate with GFPKERNEL, and wait for an RCU grace period. bpfsysclose reaches closefd and filpclose, which can sleep as wel...

CVE-2026-98046

The Linux kernel contains a vulnerability where the bpf_btf_find_by_name_kind() helper is incorrectly treated as non-sleepable. Because the helper does not set might_sleep , the BPF verifier allows its use in non-sleepable contexts like BPF timer callbacks . This can lead to a condition where ano...
