out-of-bounds read

About this tag
The out-of-bounds read tag covers Linux kernel and driver vulnerabilities where memory is read beyond allocated boundaries. Recurring themes include flaws in Bluetooth (btusb, L2CAP), USB networking (cdc_ncm), modem drivers (MediaTek T7xx), GPU components (Chrome Android), and database cluster protocols (Valkey). These bugs often arise from missing bounds checks on packet data, array indices, or descriptor offsets. While many are hardware-specific or require local access, they can lead to information disclosure, denial of service, or sandbox escape. The tag also includes older Binutils and QEDE driver fixes, reflecting a broad focus on defensive coding in kernel and system software.

  1. CVE-2026-43495 Linux Modem Driver Bug: Kernel OOB Read in MediaTek T7xx

    CVE-2026-43495 is a newly published Linux kernel vulnerability, added to NVD on May 21, 2026, in the MediaTek T7xx 5G WWAN modem driver, where malformed modem messages can trigger out-of-bounds kernel memory reads. The bug is narrow, hardware-specific, and not yet scored by NVD, but it is still...
