CVE-2026-54241— libde265: SAO sequential filter heap buffer overflow via signed integer overflow

Quick assessment

Affected
strukturag libde265
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

struktur AG libde265是struktur AG组织的一款H.265视频解码库。 struktur AG libde265 1.1.1之前版本存在安全漏洞，该漏洞源于使用有符号32位算术计算sample adaptive offset输入缓冲区大小，特制的大尺寸、16位亮度样本HEVC流可导致整数溢出、分配不足及越界堆读取，可能泄露解码输出中的堆数据或导致解码器崩溃。

Vulnerability Title
libde265: SAO sequential filter heap buffer overflow via signed integer overflow
Source: CVE Program / CVE List V5
Vulnerability Description
libde265 is an open source implementation of the h.265 video codec. Versions prior to 1.1.1 use signed 32-bit arithmetic to calculate the sample adaptive offset input-buffer size, allowing a crafted HEVC stream with large dimensions and 16-bit luma samples to cause an integer overflow, an undersized allocation, and an out-of-bounds heap read that may expose heap data in decoded output or crash the decoder. Version 1.1.1 contains a patch.
