CVE-2026-31507 net/smc: fix double-free of smc_spd_priv when tee() duplicates splice pipe buffer

In the Linux kernel, the following vulnerability has been resolved: net/smc: fix double-free of smcspdpriv when tee duplicates splice pipe buffer smcrxsplice allocates one smcspdpriv per pipebuffer and stores the pointer in pipebuffer.private. The pipebufoperations for these buffers used .get =...

CVE-2026-31507

CVE-2026-31507 affects the Linux kernel SMC module (net/smc). The vulnerability is a double-free of the per-buffer state (smc_spd_priv) when tee(2) duplicates a splice pipe buffer, leading to a use-after-free and a kernel NULL pointer dereference, ultimately causing a kernel panic. The root cause...
