The Arm Mali GPU kernel driver allows unprivileged users to access freed memory because GPU memory operations are mishandled. This affects Bifrost r0p0 through r38p1, and r39p0; Valhall r19p0 through r38p1, and r39p0; and Midgard r4p0 through r32p0.

An issue was discovered in the Arm Mali GPU Kernel Driver. A non-privileged user can make improper GPU processing operations to gain access to already freed memory, write a limited amount outside of buffer bounds, or to disclose details of memory mappings. This affects Midgard r4p0 through r32p0, Bifrost r0p0 through r38p0 and r39p0 before r38p1, and Valhall r19p0 through r38p0 and r39p0 before r38p1.

Arm Mali GPU Kernel Driver (Midgard r4p0 through r31p0, Bifrost r0p0 through r36p0 before r37p0, and Valhall r19p0 through r36p0 before r37p0) allows improper GPU memory operations to reach a use-after-free situation.

Arm Mali GPU Kernel Driver allows a non-privileged user to achieve write access to read-only memory pages. This affects Midgard r26p0 through r31p0, Bifrost r0p0 through r35p0, and Valhall r19p0 through r35p0.

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.

. The Arm Mali GPU kernel driver allows an unprivileged user to achieve access to freed memory, leading to information disclosure or root privilege escalation. This affects Bifrost r16p0 through r29p0 before r30p0, Valhall r19p0 through r29p0 before r30p0, and Midgard r28p0 through r30p0.

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.

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.

The default D-Bus access control rule in Midgard2 10.05.7.1 allows local users to send arbitrary method calls or signals to any process on the system bus and possibly execute arbitrary code with root privileges.

Multiple unspecified vulnerabilities in Midgard Components (MidCOM) Framework before 8.09.1 have unknown impact and attack vectors.
