CVE-2026-22020 is fixed in 8 products on 1 platform, first by FEDORA-2026-A109A9AC2C, released May 26, 2026. It is not reported as exploited. Patch Radar priority: Routine.
* updated to 1.6.58 * 1.6.58 is released with a fix for a simple correctness bug (not a security issue) this time: png_get_PLTE() returns stale palette data when either gamma correction or alpha-compositing is the only transform applied. Like the issues addressed in the previous release, this bug was a regression introduced in the fix for CVE-2026-33416 in 1.6.56. * 1.6.57 is released with fixes for the following security vulnerability: - CVE-2026-34757 (medium severity): Use-after-free memory bug in the chunk setter API. The hIST variant has existed since version 1.0.9, but the PLTE and tRNS ones are regressions introduced in the fix for CVE-2026-33416 in 1.6.56 (oops).
