CVE-2026-16473: Out-of-bounds Read in Red Hat Red Hat Enterprise Linux 10
A flaw was found in the sbc library (BlueZ SBC codec). An off-by-one error in the SBC frame decoder allows a crafted audio payload to trigger a one-byte heap out-of-bounds read. This could allow an adjacent attacker streaming Bluetooth audio to read a single byte of adjacent heap memory.
AI Analysis
Technical Summary
This vulnerability is an off-by-one error in the BlueZ SBC codec's frame decoder component within Red Hat Enterprise Linux 10. The flaw allows a crafted Bluetooth audio payload to trigger a one-byte heap out-of-bounds read, potentially exposing a single byte of adjacent heap memory to an attacker streaming Bluetooth audio. The CVSS 3.1 base score is 4.3, reflecting a low complexity attack vector (adjacent network), no privileges required, and limited confidentiality impact. No integrity or availability impact is indicated. The vendor advisory does not provide explicit remediation or patch information at this time.
Potential Impact
An attacker in Bluetooth proximity who can stream audio to the vulnerable system may read one byte of adjacent heap memory due to the out-of-bounds read. This results in limited confidentiality exposure without integrity or availability impact. No known exploits are reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-16473 for current remediation guidance. Until a patch is available, consider limiting Bluetooth audio streaming from untrusted devices to reduce exposure.
