CVE-2026-64253

A flaw was found in the Linux kernel. The copyprocess function, responsible for creating new processes, incorrectly inherits a flag PFBLOCKTS from the parent process while simultaneously setting a related pointer current-plug to null in the child process. This inconsistency can lead to the kernel...

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...
