Linux Kernel Security Vulnerabilities

Versions of the Linux kernel prior to 6.18.53 contain security vulnerabilities. This vulnerability stems from the serial8250register8250port function in drivers/tty/serial/8250/8250core.c, which does not perform a null pointer check when uart-port.dev is NULL. Subsequently, the hasacpicompanion...

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

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...
