Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
LoongArch: BPF: Zero-extend signed ALU32 div/mod results<br />
<br />
ALU32 operations write a 32-bit result and leave the upper 32 bits of<br />
the BPF register zero. The LoongArch JIT sign-extends the result of<br />
signed ALU32 BPF_DIV and BPF_MOD (off=1), so a negative 32-bit quotient<br />
or remainder leaves bits 63:32 set in JITted code while the verifier<br />
and interpreter model those bits as zero.<br />
<br />
Keep sign-extension on the operands, which signed divide needs, and<br />
zero-extend the ALU32 result after the divide or modulo instruction,<br />
matching the unsigned ALU32 div/mod paths and every other ALU32<br />
operation in this JIT.
