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-2022-49419

The Linux kernel contains a use-after-free vulnerability in the vesafb driver (specifically in the vesafb_remove() function). The issue arises from incorrect cleanup logic for the fb_info pointer; while a previous fix addressed cases where .fb_destroy followed .remove, a secondary scenario exists...
