Vulnerability from github – Published: 2026-03-18 18:31 – Updated: 2026-03-19 18:31

Details

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.
