A\n64-Tx/64-Rx configuration therefore records 128 vectors but allocates\nonly 64, leaving NULL entries that resource setup dereferences.\n\nInclude the maximum vector count in standalone allocation.\n\n## Affected\n\n- `Linux >= bc6107771bb4be3009168cfda24d22131c026fe8 < 9843e5fabd6ab296df9c025b1d0e5bf79a6b8a08`\n- `Linux >= bc6107771bb4be3009168cfda24d22131c026fe8 < 6c903188b67617070017305a325fa326f270a43d`\n- `Linux >= bc6107771bb4be3009168cfda24d22131c026fe8 < 16ff1023213cc39c1a7ce737205c2a1a53c3a716`\n- `Linux >= bc6107771bb4be3009168cfda24d22131c026fe8 < 1f4c73064a50f53d596c6f1d06d2d700f43c4b32`\n- `Linux 6.11`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
