CVE-2022-20367

Status: ModifiedMedium (6.7)—

In construct_transaction of lwis_ioctl.c, there is a possible out of bounds write due to an integer overflow. This could lead to local escalation of privilege in the kernel with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-225877459References: N/A
