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-2026-64250

The CVE-2026-64250 entry pertains to the Linux kernel on LoongArch. The root cause is that smp_send_stop() parks secondary CPUs and marks the offline CPU for the scheduler without informing RCU, causing RCU to wait for a quiescent state from CPUs that are spinning with interrupts disabled. The is...
