The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21612-1 advisory.

    Changes in redis:

    - Update to 8.10.1

      Update urgency: SECURITY: There are security fixes in the release.

      - Security fixes
        - (CVE-2026-62356) Miscalculated buffer size in CMSketch RDB           loading may lead to heap OOB write
        - Out-of-bounds access in TopK heap cleanup path (MOD-15410)
        - Use-after-free in the TLS pending-data list when a command           closes another pending connection
        - A malicious RDB payload with an out-of-range SLOT_INFO slot           id causes memory corruption during RDB loading, which may           lead to Remote Code Execution
        - Vector Sets: missing node level validation when loading a           vector set from RDB may lead to out-of-bounds access
        - Vector Sets: use-after-free when VREM mutates the HNSW graph           while background VSIM threads are still running
        - Vector Sets: a negative hnsw_search() return was treated as a           huge unsigned count, reading past the end of the result           arrays
        - TLS client certificate authentication bypass: a Common Name           containing an embedded NUL byte was truncated, allowing a           client to authenticate as another (possibly privileged) ACL           user
        - #15594 Use-after-free in the blocked-client list when           reprocessing a command evicts another client blocked on the           same key

    - Restrict the modules flavour to x86_64 and aarch64 -- RedisBloom and       RedisTimeSeries abort on anything else with only supports 64-bit       architectures (x64, arm64v8), redisjson's vendored redis-module is       64-bit only, and modules/common.mk maps no other architecture at all

    - Update to 8.10.0
