CVE-2026-68239

CVE-2026-68239 affects the Linux kernel DRM TTM code, specifically the ttm_pool_backup path. The issue arises because ttm_pool_backup could encounter NULL or backup handle entries (ttm_backup_page_ptr_is_handle()) which were not safely guarded for set_pages_array_wb() and could be freed erroneous...

CVE-2026-68236

CVE-2026-68236 : In the Linux kernel, the drm/amd/display path (dm_update_crtc_state) releases a stream pointer (new_stream) but fails to NULL it. If an error occurs later, the code may call dc_stream_release() again on the same dangling pointer, causing a double release and use-after-free. The f...

CVE-2026-68236 drm/amd/display: set new_stream to NULL after release

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: set newstream to NULL after release In dmupdatecrtcstate, the skipmodeset path releases newstream via dcstreamrelease but does not set the pointer to NULL. If a later error e.g., color management failure triggers...

CVE-2026-68226

The CVE affects the Linux kernel component media: cx23885. A vulnerability was resolved by adding a check for the return value of pci_ioremap_bar() in cx23885_dev_setup(). If ioremap for BAR0 fails, the code now releases the allocated PCI memory region, decrements the device count, and returns -E...
