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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/1547e9f3a7d71971216e6dba30270cae13fe4e02","tags":[]},{"url":"https://git.kernel.org/stable/c/1bd91670966a7142ac94f2cebe2b5ae6bf5cb0c8","tags":[]},{"url":"https://git.kernel.org/stable/c/6f939529ed6c580e9b6c5daa20be67fa0b3d4cf0","tags":[]},{"url":"https://git.kernel.org/stable/c/876ef04c75c2751acfd355606fca3eced71dec65","tags":[]},{"url":"https://git.kernel.org/stable/c/beeae92e70e705e90a0d6d9b3b8498ee3b92f495","tags":[]},{"url":"https://git.kernel.org/stable/c/db762fd96be225bd06161c9631160c755d891693","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
