CVE-2025-68744

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> bpf: Free special fields when update [lru_,]percpu_hash maps<br /> <br /> As [lru_,]percpu_hash maps support BPF_KPTR_{REF,PERCPU}, missing<br /> calls to &amp;#39;bpf_obj_free_fields()&amp;#39; in &amp;#39;pcpu_copy_value()&amp;#39; could cause the<br /> memory referenced by BPF_KPTR_{REF,PERCPU} fields to be held until the<br /> map gets freed.<br /> <br /> Fix this by calling &amp;#39;bpf_obj_free_fields()&amp;#39; after<br /> &amp;#39;copy_map_value[,_long]()&amp;#39; in &amp;#39;pcpu_copy_value()&amp;#39;.
