On affected versions, certain sequences of CSR operations targeting non-existent/custom CSR addresses may trigger an illegal-instruction exception but fail to reliably transfer control to the configured trap handler (mtvec), causing control-flow disruption and potentially leaving the core in a hung or unrecoverable state. This can be exploited by a local attacker able to execute code on the processor to cause a denial of service and potentially inconsistent architectural state.

Vulnerability from github – Published: 2023-04-11 21:12 – Updated: 2024-05-20 21:51Impact
Users can either intentionally or inadvertently create a keyspace containing / characters such that from that point on, anyone who tries to view keyspaces from VTAdmin will receive an error. Trying to list all the keyspaces using vtctldclient GetKeyspaces will also return an error.
Note that all other keyspaces can still be administered using the CLI (vtctldclient).
Patches
v16.0.1 (corresponding to 0.16.1 on pkg.go.dev)
Workarounds
Delete the offending keyspace using a CLI client (vtctldclient)
vtctldclient --server ... DeleteKeyspace a/b

GHSA-7587-4WV6-M68M
Vulnerability from github – Published: 2026-02-13 20:54 – Updated: 2026-02-13 20:54Summary
It was possible to trigger an unhandled edge case in the Rust Crypto rsa crate through rPGP packet parsing functionality, and crash the process that runs rPGP. This problem has been patched in a new rsa version. The new release of rPGP ensures a patched version of the rsa crate is in use, which prevents this issue.
Details
While parsing a special RSA secret key packet, rPGP calls the rsa crate with the provided key. On vulnerable versions, this results in a Rust "panic" during key construction. Note that an attacker can trigger this situation even in places where applications don't expect to handle foreign key material, for example while attempting to receive a message.
For more information on the rsa crate vulnerability, see https://github.com/RustCrypto/RSA/security/advisories/GHSA-9c48-w39g-hm26 and https://github.com/RustCrypto/RSA/pull/624. In rPGP, this has been fixed via https://github.com/rpgp/rpgp/pull/698.
Impact
This issue impacts availability (i.e. applications can crash).
Affected rPGP versions: rPGP 0.16.0-alpha.0 to 0.18.0 Vulnerable rsa versions: all before version 0.9.10
Workaround
The issue depends on the combination of affected rPGP and rsa versions. Users of affected rPGP versions can pin the patched rsa 0.9.10 via a cargo lockfile to mitigate the issue.

Discovered by Christian Reitter from Radically Open Security during a security review for Proton AG.
