Go 1.25 Release Candidate 3 is released

[Dmitri Shuralyov]

Hello gophers,

We have just released go1.25rc3, a release candidate version of Go 1.25.
It is cut from release-branch.go1.25 at the revision tagged go1.25rc3.

This release includes 2 security fixes following the security policy:

• os/exec: LookPath may return unexpected paths
  
  If the PATH environment variable contains paths which are executables (rather
  than just directories), passing certain strings to LookPath ("", ".", and ".."),
  can result in the binaries listed in the PATH being unexpectedly returned.
  
  Thanks to Olivier Mengué for reporting this issue.
  
  This is CVE-2025-47906 and Go issue https://go.dev/issue/74466.
  
  
• database/sql: incorrect results returned from Rows.Scan
  
  Cancelling a query (e.g. by cancelling the context passed to one of the query
  methods) during a call to the Scan method of the returned Rows can result in
  unexpected results if other queries are being made in parallel. This can result
  in a race condition that may overwrite the expected results with those of
  another query, causing the call to Scan to return either unexpected results
  from the other query or an error.
  
  We believe this affects most database/sql drivers.
  
  Thanks to Spike Curtis from Coder for reporting this issue.
  
  This is CVE-2025-47907 and https://go.dev/issue/74831.
