CVE-2023-52567

CVE-2023-52567 : In the Linux kernel serial driver (8250_port), if a leaf driver uses IRQ polling (irq=0) and the IIR indicates an interrupt, the IRQ data can be NULL, potentially leading to a NULL pointer dereference. The published fix adds a check to ensure IRQ data is valid before wake-up hand...

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.
