CVE-2023-51767

An authentication bypass vulnerability was found in OpenSSH. When common types of DRAM memory are used, it might allow row hammer attacks because the integer value of authenticated authpassword does not resist flips of a single bit. Mitigation Mitigation for this issue is either not available or...

ALPINE-CVE-2023-51767

OpenSSH through 10.0, when common types of DRAM are used, might allow row hammer attacks for authentication bypass because the integer value of authenticated in mmanswerauthpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim...

UBUNTU-CVE-2023-51767

OpenSSH through 9.6, when common types of DRAM are used, might allow row hammer attacks for authentication bypass because the integer value of authenticated in mmanswerauthpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim...

CVE-2023-42465

Sudo before 1.9.15 might allow row hammer attacks for authentication bypass or privilege escalation because application logic sometimes is based on not equaling an error value instead of equaling a success value, and because the values do not resist flips of a single bit...

K16842: Row hammer (rowhammer) vulnerability

Security Advisory Description Row hammer rowhammer is a problem with some recent DRAM devices, in which repeatedly accessing a row of memory can cause bit flips in adjacent rows. Impact None. F5 products are not affected by this vulnerability. Security Advisory Status F5 Product Development has...

K10631282: Flip Feng Shui (FFS) vulnerability

Security Advisory Description Flip Feng Shui FFS a new exploitation vector that allows an attacker to induce bit flips over arbitrary physical memory in a fully controlled way. FFS relies on the following underlying primitives: The ability to induce bit flips in controlled but not predetermined...

CVE-2021-42114

Modern DRAM devices PC-DDR4, LPDDR4X are affected by a vulnerability in their internal Target Row Refresh TRR mitigation against Rowhammer attacks. Novel non-uniform Rowhammer access patterns, consisting of aggressors with different frequencies, phases, and amplitudes allow triggering bit flips o...

CVE-2021-42114

CVE-2021-42114 (Blacksmith) affects modern DRAM (PC‑DDR4, LPDDR4X) where TRR mitigations can be bypassed by non‑uniform memory access patterns. ETH Zurich et al. demonstrated a fuzzer (Blacksmith) that triggered bit flips across 40 DRAM devices from major vendors (Samsung, SK Hynix, Micron), enab...

Poor Rowhammer Fixes On DDR4 DRAM Chips Re-Enable Bit Flipping Attacks

Remember rowhammer vulnerability? A critical issue affecting modern DRAM dynamic random access memory chips that could allow attackers to obtain higher kernel privileges on a targeted system by repeatedly accessing memory cells and induce bit flips. To mitigate Rowhammer vulnerability on the late...

CVE-2020-10255

Modern DRAM chips DDR4 and LPDDR4 after 2015 are affected by a vulnerability in deployment of internal mitigations against RowHammer attacks known as Target Row Refresh TRR, aka the TRRespass issue. To exploit this vulnerability, the attacker needs to create certain access patterns to trigger bit...
