Important: kernel

Issue Overview: In v4l2m2mquerybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input validation. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Andro...
