  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Fix immediate JMP JEQ/JNE on MIPS32\n\nAn addu instruction was emitted instead of addiu, causing the immediate\nvalue 1 to be interpreted as register $at. This made the comparison\nresult invalid when the immediate operand was negative. Note that $at\nis mapped to BPF_REG_AX, which is used for constant blinding.\n\nFix the instruction to use the immediate form.\n\nFound with test_bpf on MIPS32r1 emulated by QEMU.",
