An unprivileged context can trigger a data memory-dependent prefetch engine to fetch the contents of a privileged location and consume those contents as an address that is also dereferenced.
Use After Free vulnerability in Arm Ltd Valhall GPU Kernel Driver, Arm Ltd Arm 5th Gen GPU Architecture Kernel Driver allows a local non-privileged user process to perform improper GPU memory processing operations to gain access to already freed memory.This issue affects Valhall GPU Kernel Driver: from r53p0 through r54p1; Arm 5th Gen GPU Architecture Kernel Driver: from r53p0 through r54p1.
In certain circumstances, an issue in Arm Cortex-A57, Cortex-A72 (revisions before r1p0), Cortex-A73 and Cortex-A75 may allow an adversary to gain a weak form of control over the victim's branch history.
Systems with microprocessors utilizing speculative execution may allow unauthorized disclosure of information to an attacker with local user access via a side-channel attack on the directional branch predictor, as demonstrated by a pattern history table (PHT), aka BranchScope.
Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis of the data cache.
A local non-privileged user can make GPU processing operations that expose sensitive data from previously freed memory.
There is a possible disclosure of Bluetooth adapter details due to a permissions bypass. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.
An issue in hMailServer v.5.8.6 allows a local attacker to obtain sensitive information via the hmailserver/installation/hMailServerInnoExtension.iss and hMailServer.ini components.
