CVE-2026-46220

CVE-2026-46220 affects the Linux kernel’s drm/amdgpu sdma4 fence emission. The vulnerability stems from two BUG_ON(addr & 0x3) assertions in sdma_v4_0_ring_emit_fence(), which could be triggered by unprivileged userspace submissions via DRM_IOCTL_AMDGPU_CS, causing a kernel panic in a scheduler w...

CVE-2026-46220 drm/amdgpu/sdma4: replace BUG_ON with WARN_ON in fence emission

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/sdma4: replace BUGON with WARNON in fence emission sdmav40ringemitfence contains two BUGONaddr & 0x3 assertions that verify fence writeback addresses are dword-aligned. These assertions can be reached from unprivileged...

CVE-2026-45962

A flaw was found in the Linux kernel's userspace block ublk driver. This vulnerability allows a local attacker to cause an out-of-boundary memory access by providing a specially crafted command that bypasses the IOURINGFSQE128 flag check. This could lead to a system crash, resulting in a denial o...

CVE-2026-45975

A flaw was found in the Linux kernel's ublk subsystem. A local attacker could exploit a race condition where the kernel reads struct ublksrvctrlcmd from userspace-mapped memory without proper synchronization. This allows a malicious user to concurrently write to the structure, potentially causing...
