CVE-2022-23960

CVE-2022-23960 affects Arm Cortex and Neoverse processors. It is a Spectre-BHB side-channel issue where shared branch history in the Branch History Buffer can influence mispredicted branches, enabling potential information disclosure through cache allocation. Documents note mitigations include de...

CVE-2022-25368

Spectre BHB is a variant of Spectre-v2 in which malicious code uses the shared branch history stored in the CPU BHB to influence mispredicted branches in the victim's hardware context. Speculation caused by these mispredicted branches can then potentially be used to cause cache allocation, which...

CVE-2022-25368

CVE-2022-23960 describes Spectre-BHB: an attack on ARM Cortex and Neoverse CPUs that abuse the Branch History Buffer (BHB) to influence mispredicted branches, enabling a cache-related side-channel and potential information disclosure across security contexts. Affected: ARM Cortex and Neoverse pro...

UBUNTU-CVE-2022-23960

Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer BHB to influence mispredicted branches. Then, cache allocation can allow the attacker to obtai...

Race condition

A race condition in specific microprocessors using Intel R DDIO cache allocation and RDMA may allow an authenticated user to potentially enable partial information disclosure via adjacent access...

CVE-2019-11184

CVE-2019-11184 describes a race condition in Intel DDIO cache allocation with RDMA that may allow an authenticated user to cause partial information disclosure via adjacent access. The vulnerability affects microprocessors using DDIO/RDMA and is characterized by an adjacent-access exposure with m...

Fresh Spectre Variants Come to Light

Two new speculative execution bugs have earned researchers a $100,000 bug bounty from Intel. MIT’s Vladimir Kiriansky and independent researcher Carl Waldspurger uncovered what they call Spectre1.1 and a subset, Spectre1.2, collectively referred to as Variant 4 of Spectre by Intel and ARM. Like t...
