+Subject: [PATCH] Expand allocation of options string.
+
+CVE: CVE-2026-34979
+Upstream-Status: Backport [https://github.com/OpenPrinting/cups/commit/0ff8897367c7341f2500770c3977038cdd7c0214]
+
+Backport Changes:
+- Rebase scheduler/job.c IPP length context to the CUPS 2.4.11 source
+  carried by this recipe.
+- Omit the upstream CHANGES.md release-note hunk because Yocto patch metadata
+  carries the CVE details and the target source release-note sections differ.
+
+(cherry picked from commit 0ff8897367c7341f2500770c3977038cdd7c0214)
+Signed-off-by: Deepak Rathore <deeratho@cisco.com>
