EUVD-2026-315253

fkie_cve-2025-71270

In the Linux kernel, the following vulnerability has been resolved:

LoongArch: Enable exception fixup for specific ADE subcode

This patch allows the LoongArch BPF JIT to handle recoverable memory access errors generated by BPF_PROBE_MEM* instructions.

When a BPF program performs memory access operations, the instructions it executes may trigger ADEM exceptions. The kernel’s built-in BPF exception table mechanism (EX_TYPE_BPF) will generate corresponding exception fixup entries in the JIT compilation phase; however, the architecture-specific trap handling function needs to proactively call the common fixup routine to achieve exception recovery.

do_ade(): fix EX_TYPE_BPF memory access exceptions for BPF programs, ensure safe execution.

Relevant test cases: illegal address access tests in module_attach and subprogs_extable of selftests/bpf.

WID-SEC-W-2026-0790 — Linux Kernel: Mehrere Schwachstellen

Ein Angreifer kann mehrere Schwachstellen in Linux Kernel ausnutzen, um nicht näher spezifizierte Angriffe durchzuführen, die möglicherweise zu einem Denial-of-Service-Zustand, einer Rechteausweitung oder einer Speicherbeschädigung führen können.
