CVE-2021-44828
https://notcve.org/view.php?id=CVE-2021-44828
Arm Mali GPU Kernel Driver (Midgard r26p0 through r30p0, Bifrost r0p0 through r34p0, and Valhall r19p0 through r34p0) allows a non-privileged user to achieve write access to read-only memory, and possibly obtain root privileges, corrupt memory, and modify the memory of other processes. El controlador del kernel de la GPU Arm Mali (Midgard versiones r26p0 hasta r30p0, Bifrost r0p0 a r34p0, y Valhall versiones r19p0 hasta r34p0) permite a un usuario no privilegiado conseguir acceso de escritura a la memoria de sólo lectura, y posiblemente alcanzar privilegios de root, corromper la memoria y modificar la memoria de otros procesos • https://developer.arm.com/support/arm-security-updates/mali-gpu-kernel-driver • CWE-787: Out-of-bounds Write •
CVE-2021-28664 – Arm Mali Graphics Processing Unit (GPU) Unspecified Vulnerability
https://notcve.org/view.php?id=CVE-2021-28664
The Arm Mali GPU kernel driver allows privilege escalation or a denial of service (memory corruption) because an unprivileged user can achieve read/write access to read-only pages. This affects Bifrost r0p0 through r29p0 before r30p0, Valhall r19p0 through r29p0 before r30p0, and Midgard r8p0 through r30p0 before r31p0. El controlador del kernel de la GPU Arm Mali permite una escalada de privilegios o una denegación de servicio (corrupción de memoria) porque un usuario sin privilegios puede conseguir acceso de lectura/escritura a páginas de sólo lectura. Esto afecta a Bifrost r0p0 hasta r29p0 antes de r30p0, Valhall r19p0 hasta r29p0 antes de r30p0, y Midgard r8p0 hasta r30p0 antes de r31p0 Arm Mali Graphics Processing Unit (GPU) kernel driver contains an unspecified vulnerability that may allow a non-privileged user to gain write access to read-only memory, gain root privilege, corrupt memory, and modify the memory of other processes. • https://developer.arm.com/Arm%20Security%20Center/Mali%20GPU%20Driver%20Vulnerabilities https://developer.arm.com/support/arm-security-updates https://developer.arm.com/support/arm-security-updates/mali-gpu-kernel-driver • CWE-787: Out-of-bounds Write •
CVE-2021-28663 – Arm Mali Graphics Processing Unit (GPU) Use-After-Free Vulnerability
https://notcve.org/view.php?id=CVE-2021-28663
The Arm Mali GPU kernel driver allows privilege escalation or information disclosure because GPU memory operations are mishandled, leading to a use-after-free. This affects Bifrost r0p0 through r28p0 before r29p0, Valhall r19p0 through r28p0 before r29p0, and Midgard r4p0 through r30p0. El controlador del kernel de Arm Mali GPU, permite una escalada de privilegios o una divulgación de información porque las operaciones de la memoria de la GPU son manejadas inapropiadamente, conllevando a un uso de la memoria previamente liberada. Esto afecta a Bifrost versiones r0p0 hasta r28p0, anteriores a r29p0, Valhall versiones r19p0 hasta r28p0 anteriores a r29p0 y Midgard versiones r4p0 hasta r30p0 Arm Mali Graphics Processing Unit (GPU) kernel driver contains a use-after-free vulnerability that may allow a non-privileged user to make improper operations on GPU memory to gain root privilege, and/or disclose information. • https://github.com/lntrx/CVE-2021-28663 https://developer.arm.com/support/arm-security-updates https://developer.arm.com/support/arm-security-updates/mali-gpu-kernel-driver • CWE-416: Use After Free •
