Astra Linux – Vulnerability in RustC

In the standard library of Rust before version 1.2.0, BinaryHeap is not panic-safe. The binary heap becomes in an inconsistent state when the comparison of generic elements within siftup or siftdownrange causes a panic. This bug results in a decrease of zeroed memory of an arbitrary type, which c...

RUSTSEC-2026-0272 Panic-safety unsoundness in `Stack::pop`, `Fifo::pop_front` and `Value::replace_stable` (use-after-free / double-free)

Three removal and replacement paths destroy an initialized value before committing the metadata change that removes it. Destruction runs T::drop, which is user code and may panic. If it does, the commit is skipped and the container still claims ownership of the already-destroyed value, so its own...

RUSTSEC-2026-0267 Panic-safety unsoundness in `BitVecCore::clear` (double-free / use-after-free)

BitVecCore::clear drops every occupied element with dropinplace and only afterwards clears the occupancy bits and resets len. If an element's Drop panics, those metadata updates are skipped, so the slot of the already-dropped element stays marked as occupied. BitVecCore::drop calls clear again,...

block_buffer: panic corrupts inline buffer position

Summary A caught panic may leave the cursor position of EagerBuffer or ReadBuffer in a corrupted state; this in turn allows out-of-bounds reads/writes. Details & PoC The following two tests fail miri: rust cfgmiri test fn eagerdigestblockspaniccorruptsinlineposition // EagerBuffer stores its curs...

RUSTSEC-2026-0256 Panic-safety unsoundness in `truncate_back`, `truncate_front`, `clear`, and `extend_from_slice` (use-after-free / double-free)

Several methods in circular-buffer drop elements before updating the buffer's start/end metadata. If an element's Drop panics during the drop, the metadata update is skipped, so the buffer still treats the already-dropped elements as live. When the buffer is later dropped or used after the panic ...

RUSTSEC-2026-0252 Panic-safety unsoundness in `SplitVec::extend_from_slice` (uninitialized read)

SplitVec::extendfromslice increments the logical length self.len before cloning the incoming elements into the reserved slots. If an element's Clone panics mid-fill, unwinding leaves self.len counting slots that were never initialized. A later safe read get, indexing, iter then reads one of those...

RUSTSEC-2026-0254 Panic-safety unsoundness in `Chunk` and `InlineArray` (use-after-free / double-free)

Several methods in sp-sized-chunks drop elements before updating the container's length/boundary metadata. If an element's Drop panics during the drop, the metadata update is skipped, so the container still treats the already-dropped elements as live. When the container is later dropped, its own...

RUSTSEC-2026-0255 Panic-safety unsoundness in `Chunk`, `RingBuffer`, and `InlineArray` (use-after-free / double-free)

Several methods in sized-chunks drop elements before updating the length/boundary metadata. If an element's Drop panics during the drop, the metadata update is skipped, so the container still treats the already-dropped elements as live. When the container's own Drop runs, those elements are visit...

`Array::insert` violates exception safety if compare function panics, leading to potential Double-Free

In affected versions of this crate, Array::insert is not exception safe. In the UPSERT path, key and value's snapshot is written to self.datablock, and after the insertion is completed, key and value are mem::forget in order to prevent double free. However, during the insertion, K::compare is...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mptcp: fixed scheduling with atomic operations in timestamp sockopt. Using locksockfast in an atomic context around socksettimestamp and socksettimestamping is unsafe, as both helpers may cause sleep. Replace locksockfast with...

GHSA-VFVV-C25P-M7MM rkyv: Panic safety bugs in `InlineVec::clear` and `SerVec::clear` enable arbitrary code execution

InlineVec::clear and SerVec::clear in rkyv were not panic-safe. Both functions iterate over their elements and call dropinplace on each, updating self.len only after the loop. If an element's Drop implementation panics during the loop, self.len is left at its original value. A subsequent invocati...

RUSTSEC-2026-0253 Potential use-after-free due to lack of panic safety in `LruCache::pop()`

LruCache::pop in lru was not panic-safe. If the Drop implementation of a stored key panics during pop, self.detach is never called, leaving dangling pointers in the internal doubly-linked list. A subsequent cache operation that triggers eviction can then dereference these dangling pointers: - The...
