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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - rustls-webpki through 0.103.12 (and 0.104.0-alpha releases before 0.104.0-alpha.7) contains a reachable     panic in bit_string_flags() in src/der.rs. The input guard fails to reject a named-bit BIT STRING whose     content is exactly [0x00] (zero padding bits and no data bytes), so raw_bits.len() - 1 underflows on the     empty slice and the subsequent index operation panics (subtract-with-overflow in debug, index-out-of-     bounds in release). The condition is reachable through the public API     BorrowedCertRevocationList::from_der() when a CRL contains an issuingDistributionPoint extension with such     an onlySomeReasons value. Exploitation requires an application that explicitly opts in to CRL revocation     checking by passing RevocationOptions to verify_for_usage() and that parses CRL bytes obtained from a     source the attacker can influence; the default rustls configuration, which does not use RevocationOptions,     is unaffected. A crafted CRL causes a denial of service via the panic. Fixed in 0.103.13 and     0.104.0-alpha.7. (CVE-2026-93599)

Note that Nessus relies on the presence of the package as reported by the vendor.
