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.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
