CVE-2022-49713

In CVE-2022-49713, the Linux kernel vulnerability affects the USB-DWC2 HCD initialization path. The issue is a memory leak in dwc2_hcd_init where usb_create_hcd allocates memory for hcd but may fail to free it if platform_get_resource() fails; the fix moves the error path from error1 to error2 an...

CVE-2022-49512

CVE-2022-49512 affects the Linux kernel’s mtd: rawnand: denali driver. The issue arises because the driver did not use managed device resources, leading to kernel faults (example: timeout waiting for IRQ, page fault on supervisor write) when a NAND device is probed. The vulnerability is resolved ...
