CVE-2020-0189Network attack vector

Service hang via unconsumed NAL search input

Published Jun 11, 2020 · Updated Aug 4, 2024

Denial of service in the libhevc decoder in Android 10 allows remote attackers to hang media decoding through crafted HEVC data. In ihevcd_decode() in decoder/ihevcd_decode.c, a NAL search that reaches the input boundary fails to consume data or exit, so the decode loop repeats indefinitely. Exploitation requires user interaction with attacker-supplied media; the resulting resource exhaustion interrupts the affected decoding service.
