Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:4273-1 advisory.

- CVE-2026-85197: heap use-after-free in HTTP/2 `client on_data_read()` via `GOAWAY` during body upload (bsc#1279238).
- CVE-2026-85534: heap buffer overflow in `SoupSession` through `on_data_source_read_callback()` via `SETTINGS` frame with crafted `INITIAL_WINDOW_SIZE` (bsc#1279239).

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

Solution
