CVE-2026-46063
In the Linux kernel, the following vulnerability has been resolved: x86/shstk: Prevent deadlock during shstk sigreturn During sigreturn the shadow stack signal frame is popped. The kernel does this by reading the shadow stack using normal read accesses. When it can't assume the memory is shadow...

CVE-2026-46063
The CVE-2026-46063 issue affects the Linux kernel (x86/shstk) where a deadlock could occur during sigreturn while popping the shadow stack frame. The root cause was reading the shadow stack with the mmap lock held; a page fault could trigger a recursive mmap lock acquisition, risking deadlock if ...

In the Linux kernel, the following vulnerability has been resolved: x86/shstk: Prevent deadlock during shstk sigreturn During sigreturn the shadow stack signal frame is popped. The kernel does this by reading the shadow stack using normal read accesses. When it can't assume the memory is shadow...
Astra Linux - уязвимость в linux-5.10
In the Linux kernel, the following vulnerability has been resolved: bpf: Do not report a verification bug for missing bpfsccvisit calls on speculative execution paths. Syzbot generated a program that triggers a verifierbug call in maybeexitscc. maybeexitscc assumes that, when called for a state...
Astra Linux - уязвимость в xen
Potential speculative code storage bypasses exist in all supported CPU products. Combined with software vulnerabilities related to speculative execution of overwritten instructions, this could lead to incorrect speculation and potentially cause data leakage...
Astra Linux - уязвимость в linux-5.10, linux
In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed pointer-leak due to insufficient speculative store bypass mitigation To mitigate Spectre v4, the patch 2039f26f3aca “bpf: Fixed leakage due to insufficient speculative store bypass mitigation” inserts lfence instructio...
Astra Linux - уязвимость в linux-5.10
In the Linux kernel, the following vulnerability has been resolved: x86/fred: Correct speculative safety in fredextint The arrayindexnospec function is useless if the result is spilled to the stack, as it makes the supposedly safe-under-speculation value subject to memory predictions. For all...
Astra Linux - уязвимость в linux-5.10, linux-5.15, linux-6.1
In the Linux kernel, the following vulnerability has been resolved: x86/srso: Added SRSO mitigation for Hygon processors. Added mitigation for the speculative return stack overflow vulnerability, which also exists on Hygon processors...
Astra Linux - уязвимость в linux, linux-5.10
In the Linux kernel up to version 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory through a Speculative Store Bypass side-channel attack, because the protection mechanism ignores the possibility of uninitialized memory locations within the BPF stack...
Astra Linux - уязвимость в linux, linux-5.15
When SMT is enabled, certain AMD processors may speculateively execute instructions using a target from the sibling thread after a SMT mode switch, which may potentially lead to information disclosure...
Astra Linux - уязвимость в linux-6.1, linux-5.10, linux-5.15
In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Use arrayindexnospec with indices that come from the guest. min and destid are guest-controlled indices. Using arrayindexnospec after the bounds checks helps to mitigate speculative execution side-channels...

ROS-20260514-73-0001
A vulnerability in the phpreadstreamallchunks function of the PHP programming language is related to speculative command execution. Exploitation of the vulnerability could allow a remote attacker to gain access to sensitive data...
SUSE CVE-2023-20569
A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure...
CVE-2026-44223
vLLM is an inference and serving engine for large language models LLMs. From to before 0.20.0, the extracthiddenstates speculative decoding proposer in vLLM returns a tensor with an incorrect shape after the first decode step, causing a RuntimeError that crashes the EngineCore process. The crash ...
CVE-2026-44223
vLLM contains a vulnerability (CVE-2026-44223) where the extract_hidden_states speculative decoding pathway can crash the EngineCore process if any request uses penalty parameters (repetition_penalty, frequency_penalty, or presence_penalty). The issue arises from an incorrect tensor shape after t...
