CVE-2026-52910

In the Linux kernel, the following vulnerability has been resolved: bpf: Free reuseport cBPF prog after RCU grace period. Eulgyu Kim reported the splat below with a repro. 0 The repro sets up a UDP reuseport group with a cBPF prog and replaces it with a new one while another thread is sending a U...

CVE-2026-52910

The CVE-2026-52910 issue is in the Linux kernel where a cBPF reuseport program may be freed immediately when detached from a reuseport group, without waiting for an RCU grace period. This can lead to a use-after-free and potential memory corruption when a concurrent UDP send crosses the fast path...

CVE-2026-6047

LibreOffice can import documents in the OOXML format DOCX. A heap buffer overflow existed when replaying deferred parser events for a text box element. A handler object was assumed to be of one type and written to at that type's field layout, but it could be a smaller object, so the write landed...

python-zeroconf: Unbounded TC-deferred queue allows LAN-local memory exhaustion via spoofed-source flood

Impact AsyncListener.handlequeryordefer retained every truncated TC-bit incoming query in self.deferredaddr and armed a per-addr timer in self.timersaddr that flushed the reassembled query within 500 ms RFC 6762 §18.5. Neither the per-addr list nor the number of distinct addr keys was capped, and...

Xen: Use after free of paging structures in EPT (XSA-480)

The Intel EPT paging code uses an optimization to defer flushing of any cached EPT state until the p2m lock is dropped, so that multiple modifications done under the same locked region only issue a single flush. Freeing of paging structures however is not deferred until the flushing is done, and...
