In the Linux kernel through 5.4.6, there are information leaks of uninitialized memory to a USB device in the drivers/net/can/usb/kvaser_usb/kvaser_usb_leaf.c driver, aka CID-da2311a6385c.
03 Exploitation and scoring
- Exploitation
- Not assessed. CISA has not published an exploitation assessment for this record, and it is not in the KEV catalog. That is an absence of assessment, not a finding of no risk.
- SSVC decision
- Not assessed by CISA
- EPSS probability
- 0.49% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 42.0% of scored records. A rank, not a probability.
- NVD base score
- 4.6 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
- NVD analysis status
- Modified. NVD last modified this record on 2026-06-17.
- Red Hat severity
- Moderate. Red Hat's rating for its own products, not a CVSS rating.
Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.
