In the Linux kernel, the following vulnerability has been resolved: xfrm: fix stale skb-prev after async crypto steals a GSO segment skbgsosegment leaves the segment list head with -prev pointing at the last segment, an invariant validatexmitskblist relies on when it sets its tail pointer tail =...

CVE-2026-68417 RDMA/siw: publish QP after initialization

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: publish QP after initialization siwcreateqp currently calls siwqpadd before the queues, CQ pointers, state, completion, and device list entry are ready. A QPN lookup can therefore reach a QP that is still being...

CVE-2026-68417

The CVE-2026-68417 issue affects the Linux kernel RDMA/siw component. Root cause: siw_create_qp() calls siw_qp_add() before QP state/queues/CQs/completion/device list are fully initialized, allowing a QPN lookup to reach a QP still under construction. The remediation implemented in the public des...

CVE-2026-68416

In the Linux kernel, the following vulnerability has been resolved: mtd: fix double free and WARNON in addmtddevice error paths When deviceregister or mtdnvmemadd fails inside addmtddevice for a partition, the error handling triggers mtdrelease via putdevice or deviceunregister. mtdrelease calls...

CVE-2026-68412

The CVE-2026-68412 affects the Linux kernel’s wireless subsystem, specifically the cfg80211_wext_siwscan() error path. If the IEEE80211_MAX_SSID_LEN test fails, the request (creq) could leak due to improper error handling. The fix uses the existing error handling path to prevent the leak. No expl...
