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. The Linux kernel CVE team has assigned CVE-2026-98460 to this issue.

Affected files ============== The file(s) affected by this issue are: net/bluetooth/hci_sock.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/70b0a27bdde0cb524349c8261202c7c9393cf5e9 https://git.kernel.org/stable/c/598686f5d65b9af2223ed9d22fadba16e09f6ca8 https://git.kernel.org/stable/c/c1fd465ea1c5aef459f9bc3ac602b5353e0f536f https://git.kernel.org/stable/c/68f0bcc4e16e31ff8dbe6ca93116eb70d7b6ac44 https://git.kernel.org/stable/c/320dedad15e8bbaecc8d2d7fd4189defb84caa85 https://git.kernel.org/stable/c/173457fa3e99ef4188dd0fe63e4dee98d0e441a9 https://git.kernel.org/stable/c/47d67ec424e63e61e9eb58633d43a9d58a1852b6 https://git.kernel.org/stable/c/e93fad891c72deb84cae49430163b384ebcc92b1
