CVE-2024-56590
Status: ModifiedMedium (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_core: Fix not checking skb length on hci_acldata_packet
This fixes not checking if skb really contains an ACL header otherwise the code may attempt to access some uninitilized/invalid memory past the valid skb->data.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
- Base score: 5.5
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.29%
- Percentile among all scored CVEs: 20
- Score date: 10/3/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
