Exploitation

Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

libde265 的 commit 4d45a6b 中存在一个空指针解引用漏洞，位于 NAL 解析路径。当以长度为 0 的 NAL 单元调用 de265_push_NAL() 时，生成的 NAL_unit 可能保留一个空的后备缓冲区，该空指针随后在 NAL_unit::set_data() 中被作为 memcpy() 的目标参数传递。尽管复制长度为 0，但此举违反了 memcpy() 对非空指针的要求，导致未定义行为，从而在启用 UBSan 检测的构建中引发进程终止，并可能导致拒绝服务（DoS）攻击。

Vulnerability Description
libde265 commit 4d45a6b contains a NULL pointer dereference vulnerability in the NAL parsing path. When de265_push_NAL() is called with a zero-length NAL unit, the resulting NAL_unit may retain a NULL backing buffer, which is subsequently passed as the destination argument to memcpy() in NAL_unit::set_data(). Although the copy length is zero, this violates the nonnull requirement of memcpy() and results in undefined behavior, causing process termination in UBSan-instrumented builds and denial of service.
