CVE-2026-90338

A flaw was found in the Linux kernel's amba-pl011 serial driver. When the pl011consolewriteatomic function is called from an atomic context, such as during a printk operation on a PREEMPTRT kernel, it attempts to acquire a sleeping lock. This action is forbidden in an atomic context and can lead ...

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...
