error[unsound]: Unsoundness in `Error::downcast_mut()`

  ├ ID: RUSTSEC-2026-0190
  ├ Advisory: https://rustsec.org/advisories/RUSTSEC-2026-0190
  ├ Affected versions of this crate violate borrow rules, resulting in undefined behavior, when the user adds context to an error via `Error::context` and then later calls `Error::downcast_mut` on the returned `Error`.
    
    The flaw was corrected in commit `6e8c000` by revising how the mutable reference is constructed, avoiding inclusion of a shared reference in the resulting borrow chain.
    
    ## Example
    
    ```rust
    use anyhow::Error;
    use std::fmt;
    
    #[derive(Debug)]
    struct ErrorContext(&'static str);
    
    impl fmt::Display for ErrorContext {
        fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
            fmt::Display::fmt(&self.0, f)
        }
    }
    
    fn main() {
        let mut error = Error::msg("inner error").context(ErrorContext("old context"));
        let context: &mut ErrorContext = error.downcast_mut().unwrap();
        context.0 = "new context";
        println!("{:?}", error);
    }
    ```
    
    ## Miri output
    
    ```
    error: Undefined Behavior: trying to retag from <1538> for Unique permission at alloc602[0x38], but that tag only grants SharedReadOnly permission for this location

error[unsound]: Rand is unsound with a custom logger using `rand::rng()`

    ├ ID: RUSTSEC-2026-0097
    ├ Advisory: https://rustsec.org/advisories/RUSTSEC-2026-0097
    ├ It has been reported (by @lopopolo) that the `rand` library is [unsound](https://rust-lang.github.io/unsafe-code-guidelines/glossary.html#soundness-of-code--of-a-library) (i.e. that safe code using the public API can cause Undefined Behaviour) when all the following conditions are met:
      
      - The `log` and `thread_rng` features are enabled
      - A [custom logger](https://docs.rs/log/latest/log/#implementing-a-logger) is defined
      - The custom logger accesses `rand::rng()` (previously `rand::thread_rng()`) and calls any `TryRng` (previously `RngCore`) methods on `ThreadRng`
      - The `ThreadRng` (attempts to) reseed while called from the custom logger (this happens every 64 kB of generated data)
      - Trace-level logging is enabled or warn-level logging is enabled and the random source (the `getrandom` crate) is unable to provide a new seed
      
      `TryRng` (previously `RngCore`) methods for `ThreadRng` use `unsafe` code to cast `*mut BlockRng<ReseedingCore>` to `&mut BlockRng<ReseedingCore>`. When all the above conditions are met this results in an aliased mutable reference, violating the Stacked Borrows rules. Miri is able to detect this violation in sample code. Since construction of [aliased mutable references is Undefined Behaviour](https://doc.rust-lang.org/stable/nomicon/references.html), the behaviour of optimized builds is hard to predict.

      Note this library does not provide an API for asserting URI names, and URI name constraints are otherwise not implemented.  URI name constraints are now rejected unconditionally.
      
      Since name constraints are restrictions on otherwise properly-issued certificates, this bug is reachable only after signature verification and requires misissuance to exploit.

      This was incorrect because, given a name constraint of `accept.example.com`, `*.example.com` could feasibly allow a name of `reject.example.com` which is outside the constraint.

    ├ A panic was reachable when parsing certificate revocation lists via [`BorrowedCertRevocationList::from_der`]
      or [`OwnedCertRevocationList::from_der`].  This was the result of mishandling a syntactically valid empty
      `BIT STRING` appearing in the `onlySomeReasons` element of a `IssuingDistributionPoint` CRL extension.
      
      This panic is reachable prior to a CRL's signature being verified.
      
      Applications that do not use CRLs are not affected.

error[unsound]: Unsoundness in `Error::downcast_mut()`

  ├ ID: RUSTSEC-2026-0190
  ├ Advisory: https://rustsec.org/advisories/RUSTSEC-2026-0190
  ├ Affected versions of this crate violate borrow rules, resulting in undefined behavior, when the user adds context to an error via `Error::context` and then later calls `Error::downcast_mut` on the returned `Error`.
    
    The flaw was corrected in commit `6e8c000` by revising how the mutable reference is constructed, avoiding inclusion of a shared reference in the resulting borrow chain.
    
    ## Example
    
    ```rust
    use anyhow::Error;
    use std::fmt;
    
    #[derive(Debug)]
    struct ErrorContext(&'static str);
    
    impl fmt::Display for ErrorContext {
        fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
            fmt::Display::fmt(&self.0, f)
        }
    }
    
    fn main() {
        let mut error = Error::msg("inner error").context(ErrorContext("old context"));
        let context: &mut ErrorContext = error.downcast_mut().unwrap();
        context.0 = "new context";
        println!("{:?}", error);
    }
    ```
    
    ## Miri output
    
    ```

error[unsound]: Rand is unsound with a custom logger using `rand::rng()`

    ├ ID: RUSTSEC-2026-0097
    ├ Advisory: https://rustsec.org/advisories/RUSTSEC-2026-0097
    ├ It has been reported (by @lopopolo) that the `rand` library is [unsound](https://rust-lang.github.io/unsafe-code-guidelines/glossary.html#soundness-of-code--of-a-library) (i.e. that safe code using the public API can cause Undefined Behaviour) when all the following conditions are met:
      
      - The `log` and `thread_rng` features are enabled
      - A [custom logger](https://docs.rs/log/latest/log/#implementing-a-logger) is defined
      - The custom logger accesses `rand::rng()` (previously `rand::thread_rng()`) and calls any `TryRng` (previously `RngCore`) methods on `ThreadRng`
      - The `ThreadRng` (attempts to) reseed while called from the custom logger (this happens every 64 kB of generated data)
      - Trace-level logging is enabled or warn-level logging is enabled and the random source (the `getrandom` crate) is unable to provide a new seed
      
      `TryRng` (previously `RngCore`) methods for `ThreadRng` use `unsafe` code to cast `*mut BlockRng<ReseedingCore>` to `&mut BlockRng<ReseedingCore>`. When all the above conditions are met this results in an aliased mutable reference, violating the Stacked Borrows rules. Miri is able to detect this violation in sample code. Since construction of [aliased mutable references is Undefined Behaviour](https://doc.rust-lang.org/stable/nomicon/references.html), the behaviour of optimized builds is hard to predict.

  ├ ID: RUSTSEC-2026-0190
  ├ Advisory: https://rustsec.org/advisories/RUSTSEC-2026-0190
  ├ Affected versions of this crate violate borrow rules, resulting in undefined behavior, when the user adds context to an error via `Error::context` and then later calls `Error::downcast_mut` on the returned `Error`.
    
    The flaw was corrected in commit `6e8c000` by revising how the mutable reference is constructed, avoiding inclusion of a shared reference in the resulting borrow chain.
    
    ## Example
    
    ```rust
    use anyhow::Error;
    use std::fmt;
    
    #[derive(Debug)]
    struct ErrorContext(&'static str);
    
    impl fmt::Display for ErrorContext {
        fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
            fmt::Display::fmt(&self.0, f)
        }
    }
    
    fn main() {
        let mut error = Error::msg("inner error").context(ErrorContext("old context"));
        let context: &mut ErrorContext = error.downcast_mut().unwrap();
        context.0 = "new context";
        println!("{:?}", error);
    }
    ```
    
    ## Miri output
    
    ```

    ├ Advisory: https://rustsec.org/advisories/RUSTSEC-2026-0097
    ├ It has been reported (by @lopopolo) that the `rand` library is [unsound](https://rust-lang.github.io/unsafe-code-guidelines/glossary.html#soundness-of-code--of-a-library) (i.e. that safe code using the public API can cause Undefined Behaviour) when all the following conditions are met:
      
      - The `log` and `thread_rng` features are enabled
      - A [custom logger](https://docs.rs/log/latest/log/#implementing-a-logger) is defined
      - The custom logger accesses `rand::rng()` (previously `rand::thread_rng()`) and calls any `TryRng` (previously `RngCore`) methods on `ThreadRng`
      - The `ThreadRng` (attempts to) reseed while called from the custom logger (this happens every 64 kB of generated data)
      - Trace-level logging is enabled or warn-level logging is enabled and the random source (the `getrandom` crate) is unable to provide a new seed
      
      `TryRng` (previously `RngCore`) methods for `ThreadRng` use `unsafe` code to cast `*mut BlockRng<ReseedingCore>` to `&mut BlockRng<ReseedingCore>`. When all the above conditions are met this results in an aliased mutable reference, violating the Stacked Borrows rules. Miri is able to detect this violation in sample code. Since construction of [aliased mutable references is Undefined Behaviour](https://doc.rust-lang.org/stable/nomicon/references.html), the behaviour of optimized builds is hard to predict.

    ├ Permitted subtree name constraints for DNS names were accepted for certificates asserting a wildcard name.
      
      This was incorrect because, given a name constraint of `accept.example.com`, `*.example.com` could feasibly allow a name of `reject.example.com` which is outside the constraint.
      This is very similar to [CVE-2025-61727](https://go.dev/issue/76442).

P2 Badge Compare container_debug before merging payloads

When callers pass V07 payloads with this field populated, coalesce_send_data() still invokes TracerPayloadCollection::merge(), which treats payloads as equal via cmp_send_data_payloads() without looking at container_debug and then appends one payload's chunks into the other while dropping its top-level fields. Two payloads with different container tag resolution errors/latencies will therefore be sent as one payload with only the retained payload's debug value, misreporting the new diagnostics for the chunks from the dropped payload; include container_debug in the merge key or avoid merging when it differs.

P2 Badge Omit absent container debug from msgpack payloads

When sending V07 payloads through send_with_msgpack, every locally constructed tracer payload currently sets this field to None; because the generated serde field has no skip_serializing_if, rmp_serde::to_vec_named emits a container_debug: nil entry instead of omitting it, despite the new proto tag being omitempty. That changes the v0.7 wire map for all agentless sends even when no debug data exists, so please generate #[serde(skip_serializing_if = "Option::is_none")] for this field.

P2 Badge Default omitted ContainerDebug subfields

When a Serde-encoded v0.7 payload includes container_debug but omits any of its omitempty subfields (for example a successful lookup may send only latency/buffering data and omit error), deserialization will fail because the nested ContainerDebug fields are still required. The Option here only handles the whole container_debug field being absent; please add #[serde(default)] for the ContainerDebug fields/type in the generator so Rust accepts the same partial payloads allowed by the proto/go tags.
