USN-7295-1 linux-xilinx-zynqmp vulnerabilities

Ye Zhang and Nicolas Wu discovered that the iouring subsystem in the Linux kernel did not properly handle locking for rings with IOPOLL, leading to a double-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code...

CVE-2022-49724

CVE-2022-49724 affects the Linux kernel’s goldfish TTY driver. The bug arises from passing an incorrect dev_id to free_irq() during driver removal, which can lead to a splat and attempts to free an already-free IRQ (IRQ 65). A fix was implemented to pass the correct dev_id in the remove path (gol...
