SUSE CVE-2026-31507

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

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SMC module. A local user can exploit this vulnerability by using the tee2 system call to duplicate a splice pipe buffer, leading to a double-free condition. This double-free can result in a use-after-free error and a kern...

USN-8201-1: Linux kernel (Azure) vulnerabilities

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...

kernel: smc: Use __sk_dst_get() and dst_dev_rcu() in smc_clc_prfx_match()

A flaw was found in the Linux kernel’s SMC Shared Memory Communication module: in smcclcprfxmatch, the function is called from smclistenwork without proper RCU or RTNL protection. The code previously used skdstgetsk-dev, which can lead to a use-after-free UAF condition if the sk’s destination is...
