EUVD-2022-54619

In the Linux kernel, the following vulnerability has been resolved: serial: 8250: Fix PM usagecount for console handover When console is enabled, univ8250consolesetup calls serial8250consolesetup before .dev is set to uartport. Therefore, it will not call pmruntimegetsync. Later, when the actual...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The Linux kernel before version 5.8 is vulnerable to a NULL pointer dereference in drivers/tty/serial/8250/8250core.c:serial8250isainitports that allows local...

CVE-2022-49613

CVE-2022-49613 affects the Linux kernel serial driver 8250 console handover. When a console is enabled, univ8250_console_setup() runs before .dev is bound to the uart_port, so pm_runtime_get_sync() is skipped. Later, during handover, serial8250_console_exit() may call pm_runtime_put_sync() with a...

CVE-2024-43893

A divide by zero vulnerability was found in the uartgetdivisor function in the Linux Kernel's serial core subsystem. This issue is caused by the improper handling of invalid baud rates. When an invalid baudbase is specified using the TIOCSSERIAL ioctl command, if uartclk is zero, a subsequent cal...

CVE-2024-43893 serial: core: check uartclk for zero to avoid divide by zero

In the Linux kernel, the following vulnerability has been resolved: serial: core: check uartclk for zero to avoid divide by zero Calling ioctl TIOCSSERIAL with an invalid baudbase can result in uartclk being zero, which will result in a divide by zero error in uartgetdivisor. The check for uartcl...

CVE-2023-52567 serial: 8250_port: Check IRQ data before use

In the Linux kernel, the following vulnerability has been resolved: serial: 8250port: Check IRQ data before use In case the leaf driver wants to use IRQ polling irq = 0 and IIR register shows that an interrupt happened in the 8250 hardware the IRQ data can be NULL.
