"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nLoongArch: Enable exception fixup for specific ADE subcode\n\nThis patch allows the LoongArch BPF JIT to handle recoverable memory\naccess errors generated by BPF_PROBE_MEM* instructions.\n\nWhen a BPF program performs memory access operations, the instructions\nit executes may trigger ADEM exceptions. The kernel’s built-in BPF\nexception table mechanism (EX_TYPE_BPF) will generate corresponding\nexception fixup entries in the JIT compilation phase; however, the\narchitecture-specific trap handling function needs to proactively call\nthe common fixup routine to achieve exception recovery.\n\ndo_ade(): fix EX_TYPE_BPF memory access exceptions for BPF programs,\nensure safe execution.\n\nRelevant test cases: illegal address access tests in module_attach and\nsubprogs_extable of selftests/bpf."
