Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.5.0-41-generic #41~22.04.2-Ubuntu
Description:
A vulnerability in the Linux kernel's AMDGPU module has been resolved. The issue was causing a UBSAN warning in DML2.1 when programming phantom pipe, due to an unsigned integer overflow. This occurred because the
cursor width is explicitly set to 0, triggering calculation logic to overflow for an unsigned int. The kernel's UBSAN check was triggered, resulting in a shift-out-of-bounds error.Recommendations:
To resolve this issue, update the Linux kernel to a version newer than 6.5.0-41-generic #41~22.04.2-Ubuntu. As a temporary workaround, consider adding a guard for checking
cursor width before triggering the size calculation to prevent the unsigned integer overflow.Exploit
