In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/gfx10: replace BUGON with WARNON There's no need to crash the kernel for these cases. cherry picked from commit ac6f00beb658239bced4aaed9efbb04a35348d48...

CVE-2026-68107

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vcn4: avoid rereading IB param length Reuse the parameter length returned by vcnv40encfindibparam instead of rereading it from the IB. This avoids a potential TOCTOU issue if the IB contents change between reads. cherr...

In the Linux kernel, the following vulnerability has been resolved: IB/mad: Drop unmatched RMPP responses before reassembly Kernel-handled RMPP receive processing starts reassembly for active DATA responses before the response is matched to an outstanding send. The normal match happens later, aft...

CVE-2026-68418

CVE-2026-68418 affects the Linux kernel RDMA/irdma path, specifically QP creation. The root cause was that iwqp->iwpbl could be dereferenced unconditionally later in irdma_setup_virt_qp if a user supplied req.user_wqe_bufs, even when it was zero. Although there was a NULL check, it only applie...

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...
