CVE-2026-98460: Bluetooth: hci_sock: reject out-of-range OCF values

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 173457fa3e99ef4188dd0fe63e4dee98d0e441a9, 320dedad15e8bbaecc8d2d7fd4189defb84caa85, 47d67ec424e63e61e9eb58633d43a9d58a1852b6; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.159.1-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 173457fa3e99ef4188dd0fe63e4dee98d0e441a9, 320dedad15e8bbaecc8d2d7fd4189defb84caa85, 47d67ec424e63e61e9eb58633d43a9d58a1852b6; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.159.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_sock: reject out-of-range OCF values The raw HCI socket security filter has 128 OCF bits per supported OGF, but masks the 10-bit OCF with 127 before looking up the command. An unprivileged socket can therefore submit a reserved OCF that aliases an allowlisted command modulo 128. A conforming controller should reject reserved opcodes. Nevertheless, the security decision must apply to the opcode that will actually be sent, especially since controller-specific behavior is outside the host stack's control. Reject OCF values that cannot be represented by the security filter instead of aliasing them onto an unrelated command.
