CVE-2023-53680

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> NFSD: Avoid calling OPDESC() with ops-&gt;opnum == OP_ILLEGAL<br /> <br /> OPDESC() simply indexes into nfsd4_ops[] by the op&amp;#39;s operation<br /> number, without range checking that value. It assumes callers are<br /> careful to avoid calling it with an out-of-bounds opnum value.<br /> <br /> nfsd4_decode_compound() is not so careful, and can invoke OPDESC()<br /> with opnum set to OP_ILLEGAL, which is 10044 -- well beyond the end<br /> of nfsd4_ops[].
