CVE-2026-52943

CVE-2026-52943 affects the Linux kernel: two pskb_carve helpers (pskb_carve_inside_header and pskb_carve_inside_nonlinear) copy the old skb_shared_info header via memcpy without calling net_zcopy_get() for the new copy, creating an unaccounted destructor_arg (uarg) reference. This can cause use-a...
