Answer in brief
CVE-2023-52766 records a High severity (CVSS 7.8) vulnerability in i3c: mipi-i3c-hci: Fix out of bounds access in hci_dma_irq_handler. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: i3c: mipi-i3c-hci: Fix out of bounds access in hci_dma_irq_handler Do not loop over ring headers in hci_dma_irq_handler() that are not allocated and enabled in hci_dma_init(). Otherwise out of bounds access will occur from rings->headers[i] access when i >= number of allocated ring headers.
