Security issues fixed:

- CVE-2026-97033: `cmd/go`: unexpected code execution via `--sysroot`, `-target`, `-isysroot`, `-Wl,-syslibroot`, and `-x cgo` flags (bsc#1289978).
- CVE-2026-97034: `cmd/go`: arbitrary command execution via GCC spec files in `cgo` linker search directories (bsc#1289979).
- CVE-2026-97035: `cmd/go`: unexpected code execution and arbitrary file write via Clang `-gen-*` and GCC `-gnat*` flags in `cgo` (bsc#1289980).
- CVE-2026-97036: `cmd/go`: arbitrary code execution during build on darwin via `-l to_library` in `cgo` (bsc#1289981).
- CVE-2026-97037: `cmd/go`: linker script injection via split `-Wl,` flags and Darwin or symbol linker flags in `cgo` (bsc#1289982).
- CVE-2026-97038: `cmd/go`: arbitrary code execution via crafted `.syso` files and `cgo` linker input files (bsc#1289983).
- CVE-2026-97039: `cmd/go`: flag sanitization bypass via `#cgo pkg-config:` directives (bsc#1289984).
- CVE-2026-97040: `cmd/go`, `cmd/link`: `cgo` directive injection via `.syso` files disguised as Go object files (bsc#1289985).
- CVE-2026-97041: `cmd/compile`, `cmd/link`: host linker flag injection via `//go:cgo_*` directives (bsc#1289986).
- CVE-2026-97042: `cmd/cgo`, `cmd/compile`, `cmd/link`: linker flag injection via `cgo_import_dynamic` and PE DLL names (bsc#1289987).
- CVE-2026-97043: `cmd/go`, `cmd/compile`: unexpected code execution via escaped quotes in `//go:cgo_ldflag` (bsc#1289988).
- CVE-2026-97054: `net/http`: HTTP/1 server crash due to `MaxBytesReader` header race (bsc#1289989).

Changes for go1.26:

Update to version go1.26.11 (bsc#1255111):

- go#81865 `cmd/compile`: `branchelim` optimization can eliminate result of store
- go#81869 `cmd/compile`: generic shift-by-constant canonicalization gives `Const64` the wrong type
- go#81926 `cmd/asm`: amd64 assembler loops forever on a forward jump to a labelled `PCALIGN` when a branch needs widening
- go#81946 `net/http`: backport fix to protect against middleware changing server response body
- go#82022 `net`: `Dialer.Dial{TCP,UDP,IP}` incorrectly treats invalid addresses as `::`
- go#82149 `runtime`: linux/mips `time64` nanosecond layout causes busy waits and empty CPU profiles
- go#82333 `cmd/dist`: `GOFIPS140` bootstrap from Go 1.26 fails
- go#82626 `crypto/fips140`: minor compliance improvements
- go#82642 `cmd/compile`: ICE on 386 when inlining nested bit rotations (`Int64Lo` not lowered)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected go1.26, go1.26-doc and / or go1.26-race packages.
