Published: April 21, 2026
Breakdown by Severity
- Low
- Medium
- High
- Critical
Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: N/A)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within DrawArrays and AddToParent in the GPU shader compiler library. A remote unauthenticated attacker can trigger stack-based buffer overflow and cause a denial of service condition on the target system.
2) Buffer overflow (CVE-ID: N/A)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to Dmabuf imports can be used to create a freelist. A remote user can cause arbitrary physical address overwrite and execute arbitrary code on the target system.
3) NULL pointer dereference (CVE-ID: N/A)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within GLES3BinaryProgramData::ppszNameList in glCopyBufferSubData in the GPU GLES user-space shared library. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
4) Information disclosure (CVE-ID: N/A)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application within RGXCreateFreeList. A remote user can gain access to system physical page addresses.
5) Use-after-free (CVE-ID: N/A)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within llvm::UFWriterVolcanic::GenerateKernels in the GPU shader compiler library. A remote attacker can perform a denial of service (DoS) attack on the system.
6) Buffer overflow (CVE-ID: N/A)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within AllocateInst in the GPU shader compiler library. A remote attacker can trigger memory corruption and cause a denial of service condition on the target system.
