Page history
Changes are dated when recorded; day views use the last saved version from that UTC day, and citations stay fixed.
CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.
No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

bpf: Mark sched_process_wait argument as nullable
In the Linux kernel, the following vulnerability has been resolved:
bpf: Mark sched_process_wait argument as nullable
do_wait() passes wo->wo_pid to the sched_process_wait tracepoint.
kernel_wait4() leaves wo_pid NULL for wait4(-1), and
kernel_waitid_prepare() does likewise for waitid(P_ALL).
btf_ctx_access() currently types argument 0 as PTR_TO_BTF_ID |
PTR_TRUSTED. Without PTR_MAYBE_NULL, the verifier accepts an unchecked
dereference. Trusted pointer loads have no fault protection, so a wait for
any child can then cause a NULL pointer dereference in JITed BPF code.
Add sched_process_wait to raw_tp_null_args[] with argument 0 marked
nullable. The verifier rejects an unchecked dereference while preserving
access after the program checks the pointer for NULL.
