CVE-2026-64253

In the Linux kernel, the following vulnerability has been resolved: kernel/fork: clear PFBLOCKTS in copyprocess PFBLOCKTS is only set in blktimegetns when current-plug is non-NULL, and blkfinishplug clears it via blkflushplug before NULLing the plug pointer. copyprocess breaks the invariant by...

CVE-2026-64253

CVE-2026-64253 affects the Linux kernel and relates to process creation via fork. The root cause is that in copy_process(), PF_BLOCK_TS can be inherited from the parent while the child’s plug pointer is cleared, breaking the invariant that PF_BLOCK_TS set implies current->plug != NULL. The fix...

CVE-2026-64244

In the Linux kernel's drivers/base/memory , mem->altmap is assigned before __add_memory_block() completes. If xa_store() fails (e.g., under memory pressure), device_unregister() triggers memory_block_release() with altmap still set, causing a WARN_ON. The fix delays altmap assignment until aft...
