CVE-2026-90338

CVE-2026-90338 affects the Linux kernel AMBA PL011 serial console driver. The root cause is that pl011_console_write_atomic() calls clk_enable(), which acquires the common-clock enable_lock. Under PREEMPT_RT , this lock can sleep on contention, but atomic (nbcon) context forbids sleeping, trigger...

CVE-2026-90304

CVE-2026-90304 affects the Linux kernel on ARM architectures. The vulnerability resides in the exception handlers do_DataAbort() and do_PrefetchAbort() , where PREEMPT_RT requires interrupts to be enabled when sending signals. However, when an unhandled user fault is triggered (i.e., the hook fun...

CVE-2026-90305

CVE-2026-90305 affects the Linux kernel on ARM when PREEMPT_RT is enabled. The root cause is that commit c6e61c06d606 enabled PREEMPT_RT on ARM without selecting HAVE_POSIX_CPU_TIMERS_TASK_WORK , leaving CPU timers to expire in hard IRQ context . On PREEMPT_RT, this causes run_posix_cpu_timers() ...
