instead of manual match arms\n * Add support for arg files in Rust (#2782)\n * feat: support S3 SSE-KMS with AWS-managed and customer-managed keys (#2770)\n * abort compile tasks and associated subprocesses when a client disconnects\n * treat -ivfsoverlay as a preprocessor-only argument\n * gcc: refine response-file tokenizer visibility and whitespace handling\n * integration: convert cmake 4.x modules XFAIL test to a passing test\n * gcc/clang: cache and distribute builds using quoted @response files\n * fix: Fix ToolchainPackager cfg gate to build on ppc64le/s390x\n * fix: make gcc diagnostics color output work the same as for rustc\n * implement client-side mode\n * split handle_compile_response so that the compilation result can be handled \n   separately\n * implement IpcStorage -- Storage backend over IPC\n * extend wire protocol with storage RPCs\n * implement AddAssign for ServerStats and related types\n * add Storage::get_path for direct file access\n * implement get_raw/put_raw on MultiLevelStorage\n * add client_side_mode config flag (SCCACHE_CLIENT_SIDE)\n * Extract new_client_runtime() helper to DRY up client runtime creation\n * Clarify single-threaded runtime rationale comment (grammar)\n * fix: use single-threaded tokio runtime in sccache dist-client\n * fix: use single-threaded tokio runtime in sccache client\n * fix: handle disabled cache backend features in multilevel chain\n * Fix ldd output parsing: remove .exists() check that failed on systems where the \n   symlink source path does not exist locally (e.g. aarch64)\n * Fix cfg guard for PanicToolchainPackager to also cover non-x86_64 Linux \n   architectures (e.g. aarch64)\n","modified":"2026-08-22T09:45:05.710262933Z","published":"2026-08-21T09:04:42Z","related":["CVE-2026-25541","CVE-2026-66746","CVE-2026-66754","CVE-2026-67181","CVE-2026-67182"],"upstream":["CVE-2026-25541","CVE-2026-66746","CVE-2026-66754","CVE-2026-67181","CVE-2026-67182"],"references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2026/suse-su-20263674-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1273881"},{"type":"REPORT","url":"https://bugzilla.suse.com/1273884"},{"type":"REPORT","url":"https://bugzilla.suse.com/1273886"},{"type":"REPORT","url":"https://bugzilla.suse.com/1273888"},{"type":"REPORT","url":"https://bugzilla.suse.com/1274146"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2026-25541"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2026-66746"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2026-66754"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2026-67181"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2026-67182"}],"affected":[{"package":{"name":"sccache","ecosystem":"SUSE:Linux Enterprise Module for Development Tools 15 SP7","purl":"pkg:rpm/suse/sccache&distro=SUSE%20Linux%20Enterprise%20Module%20for%20Development%20Tools%2015%20SP7"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.17.0~1-150600.10.14.1"}]}],"ecosystem_specific":{"binaries":[{"sccache":"0.17.0~1-150600.10.14.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2026:3674-1.json"}},{"package":{"name":"sccache","ecosystem":"SUSE:Linux Enterprise Server 15 SP6-LTSS","purl":"pkg:rpm/suse/sccache&distro=SUSE%20Linux%20Enterprise%20Server%2015%20SP6-LTSS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.17.0~1-150600.10.14.1"}]}],"ecosystem_specific":{"binaries":[{"sccache":"0.17.0~1-150600.10.14.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2026:3674-1.json"}},{"package":{"name":"sccache","ecosystem":"SUSE:Linux Enterprise Server for SAP Applications 15 SP6","purl":"pkg:rpm/suse/sccache&distro=SUSE%20Linux%20Enterprise%20Server%20for%20SAP%20Applications%2015%20SP6"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.17.0~1-150600.10.14.1"}]}],"ecosystem_specific":{"binaries":[{"sccache":"0.17.0~1-150600.10.14.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2026:3674-1.json"}}],"schema_version":"1.9.0"}
