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

Exploitation probability (EPSS)

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).
