An index\nequal to txq->count is one past the end of both arrays, so reject it in\nthe bounds check.\n\n## Affected\n\n- `Linux >= 6e65a09f927566f257322358d429b267548473eb < 08704ec6d4bf69725e7815b09a9b5c7af83e255b`\n- `Linux >= 6e65a09f927566f257322358d429b267548473eb < 39ab048cce70d50af48015f5f294c4cf80d6ba89`\n- `Linux >= 6e65a09f927566f257322358d429b267548473eb < 2669567615215d52fb306053cbcc1f53dc386158`\n- `Linux >= 6e65a09f927566f257322358d429b267548473eb < baa53af641c9e3644e717b8dfd1b95a55a0c111b`\n- `Linux 6.10`\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":[]}
