This\nattribute is used in bounds checking, and if it is not set before the\narray is filled, then the bounds sanitizer will issue a warning or a\nkernel panic if CONFIG_UBSAN_TRAP is set.\n\nThis patch sets the size of allocated memory as the initial value for\nn_channels. It is updated with the actual number of added elements after\nthe array is filled.\n\n## Affected\n\n- `Linux >= aa4ec06c455d0200eea0a4361cc58eb5b8bf68c4 < d4ef643ea78c59c22546046c25dc6e7206267672`\n- `Linux >= aa4ec06c455d0200eea0a4361cc58eb5b8bf68c4 < 1a7b62ddf2c7642878c24f0e556041bb58c37527`\n- `Linux >= aa4ec06c455d0200eea0a4361cc58eb5b8bf68c4 < 9c46a3a5b394d6d123866aa44436fc2cd342eb0d`\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":[]}
