If the conversion\nfails, the drop path leaves the slot claimed.\n\nWith a one-frame TPACKET_V2 ring, an unsupported UDP GSO packet leaves\nthe only slot unavailable, so the ring also drops the next valid packet.\n\nClear the ownership bit on this error path.  TPACKET_V3 already clears\nits block state here.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/23cd30498891d29a69ec9b75bd92f8a0f21f1342","tags":[]},{"url":"https://git.kernel.org/stable/c/2daa618e7ff19eefcbda281bc4c5998c4140f9cf","tags":[]},{"url":"https://git.kernel.org/stable/c/33ff111d7ba3beb86e28938d6382bb5beabd865a","tags":[]},{"url":"https://git.kernel.org/stable/c/49a48a5aaf85fe69d2dc3fb334b4854fadf44e39","tags":[]},{"url":"https://git.kernel.org/stable/c/693209a237fc548791cf402441db8b68d1da7d38","tags":[]},{"url":"https://git.kernel.org/stable/c/805edbdcb8681da5f7ee43b3c3c809f7a8c31208","tags":[]},{"url":"https://git.kernel.org/stable/c/b8c0cb3069058c2d67b5c7c833b2833381ecffdc","tags":[]},{"url":"https://git.kernel.org/stable/c/bb10a0084c03a94364aeec542beddc5d49b59f59","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
