Hi @m4b4

This is related to one other POC - CVE-2023-6241

I tried the exploit for CVE-2023-6241
(https://github.com/github/securitylab/tree/main/SecurityExploits/Android/Mali/CVE_2023_6241).
It works perfectly fine on Pixel 8.

But, when I tried extending that to other vulnerable non-Pixel devices, it showed an error - CANNOT FIND REUSED PAGE:: ILLEGAL SEEK.

Is that something related to the defined TEST_VALUE=0x42424242 ? Or anything else?

I tested with Poco X6 Pro, Nothing Phone 2a, and Redmi Note 13 Pro+ by adding the offsets. All phones had the same error.

AND

Some devices with lower GPU revision levels with r32p1 give this error - BAD FILE DESCRIPTOR

Please help me with this.
