CVE-2026-64528

A flaw was found in the Linux kernel's Samsung serial driver. When console flow control is enabled, a redundant attempt to acquire a port lock occurs within the receive helper functions. This can lead to a deadlock on the same CPU, causing the system to become unresponsive...

CVE-2026-64528

The CVE-2026-64528 issue is a deadlock in the Linux kernel’s Samsung UART driver when console flow control (UPF_CONS_FLOW) is enabled. The serial core holds port->lock when invoking .stop_tx()/.start_tx(), and internal paths like DMA TX completion and TX IRQ handlers also acquire port->lock...

PT-2026-64759

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A deadlock occurs in the Samsung serial driver when console flow control is enabled via UPF CONS FLOW. The issue arises because the functions s3c24xx serial stop tx and s3c24xx serial...

CVE-2023-53687

In the Linux kernel, the following vulnerability has been resolved: tty: serial: samsungtty: Fix a memory leak in s3c24xxserialgetclk when iterating clk When the best clk is searched, we iterate over all possible clk. If we find a better match, the previous one, if any, needs to be freed. If a...

kernel: tty: serial: samsung_tty: Fix a memory leak in s3c24xx_serial_getclk() in case of error

A memory leak vulnerability was found in the Samsung serial TTY driver in the Linux kernel. In s3c24xxserialgetclk, when clkgetrate fails, the previously allocated clock resource is not freed, leading to a memory leak. Repeated failures can cause resource exhaustion...
