CVE-2026-90338 serial: amba-pl011: keep console clock enabled for atomic writes

In the Linux kernel, the following vulnerability has been resolved: serial: amba-pl011: keep console clock enabled for atomic writes pl011consolewriteatomic runs from nbcon atomic context, where sleeping is not allowed. It calls clkenable, which takes the common-clk enablelock. Under PREEMPTRT th...

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-2026-80737

This vulnerability affects the amba-pl011 UART driver in the Linux kernel . During DMA teardown, dmaengine_terminate_all() does not wait for a running callback, allowing the TX callback to access the TX buffer after it has been freed (use-after-free). Additionally, the RX poll timer reads RX buff...
