CVE-2026-1679 (GCVE-0-2026-1679)
Vulnerability from nvd – Published: 2026-03-27 23:21 – Updated: 2026-04-01 13:52
VLAI?
Title
net: eswifi socket send payload length not bounded
Summary
The eswifi socket offload driver copies user-provided payloads into a fixed buffer without checking available space; oversized sends overflow `eswifi->buf`, corrupting kernel memory (CWE-120). Exploit requires local code that can call the socket send API; no remote attacker can reach it directly.
Severity ?

CVE-2026-1678 (GCVE-0-2026-1678)
Vulnerability from nvd – Published: 2026-03-05 06:21 – Updated: 2026-03-05 15:28
VLAI?
Title
dns: memory‑safety issue in the DNS name parser
Summary
dns_unpack_name() caches the buffer tailroom once and reuses it while appending DNS labels. As the buffer grows, the cached size becomes incorrect, and the final null terminator can be written past the buffer. With assertions disabled (default), a malicious DNS response can trigger an out-of-bounds write when CONFIG_DNS_RESOLVER is enabled.

CVE-2025-10456 (GCVE-0-2025-10456)
Vulnerability from nvd – Published: 2025-09-19 05:21 – Updated: 2025-09-19 11:57
VLAI?
Title
Bluetooth: Semi-Arbitrary ability to make the BLE Target send disconnection requests
Summary
A vulnerability was identified in the handling of Bluetooth Low Energy (BLE) fixed channels (such as SMP or ATT). Specifically, an attacker could exploit a flaw that causes the BLE target (i.e., the device under attack) to attempt to disconnect a fixed channel, which is not allowed per the Bluetooth specification. This leads to undefined behavior, including potential assertion failures, crashes, or memory corruption, depending on the BLE stack implementation.
Severity ?
7.1 (High)
CWE

Summary
In DA, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege, if an attacker has physical access to the device, with no additional execution privileges needed. User interaction is needed for exploitation. Patch ID: ALPS09915215; Issue ID: MSV-3801.

CVE-2026-1679 (GCVE-0-2026-1679)

Title
net: eswifi socket send payload length not bounded
Summary
The eswifi socket offload driver copies user-provided payloads into a fixed buffer without checking available space; oversized sends overflow `eswifi->buf`, corrupting kernel memory (CWE-120). Exploit requires local code that can call the socket send API; no remote attacker can reach it directly.
Severity ?
7.3 (High)
CWE
- CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

Title
dns: memory‑safety issue in the DNS name parser
Summary
dns_unpack_name() caches the buffer tailroom once and reuses it while appending DNS labels. As the buffer grows, the cached size becomes incorrect, and the final null terminator can be written past the buffer. With assertions disabled (default), a malicious DNS response can trigger an out-of-bounds write when CONFIG_DNS_RESOLVER is enabled.

CVE-2025-10456 (GCVE-0-2025-10456)
Vulnerability from cvelistv5 – Published: 2025-09-19 05:21 – Updated: 2025-09-19 11:57
VLAI?
Title
Bluetooth: Semi-Arbitrary ability to make the BLE Target send disconnection requests
Summary
A vulnerability was identified in the handling of Bluetooth Low Energy (BLE) fixed channels (such as SMP or ATT). Specifically, an attacker could exploit a flaw that causes the BLE target (i.e., the device under attack) to attempt to disconnect a fixed channel, which is not allowed per the Bluetooth specification. This leads to undefined behavior, including potential assertion failures, crashes, or memory corruption, depending on the BLE stack implementation.

CVE-2025-10457 (GCVE-0-2025-10457)
Vulnerability from cvelistv5 – Published: 2025-09-19 05:17 – Updated: 2025-09-19 13:09
VLAI?
Title
Bluetooth: Out-Of-Context le_conn_rsp Handling
Summary
The function responsible for handling BLE connection responses does not verify whether a response is expected—that is, whether the device has initiated a connection request. Instead, it relies solely on identifier matching.
Severity ?
4.3 (Medium)
CWE

Summary
In DA, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege, if an attacker has physical access to the device, with no additional execution privileges needed. User interaction is needed for exploitation. Patch ID: ALPS09915215; Issue ID: MSV-3801.
