Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: RISCV: Sanitizing syscall table indexing under speculation The syscall number is a user-controlled value used to index into the syscall table. Use arrayindexnospec to clamp this value after the bounds check, to prevent speculativ...
CVE-2024-36315
Improper enforcement of the LFENCE serialization property may allow an attacker to bypass speculation barriers and potentially disclose sensitive information, potentially resulting in loss of confidentiality...
SUSE CVE-2024-50102
In the Linux kernel, the following vulnerability has been resolved: x86: fix user address masking non-canonical speculation issue It turns out that AMD has a "Meltdown Litetm" issue with non-canonical accesses in kernel space. And so using just the high bit to decide whether an access is in user...
UBUNTU-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...

Astra Linux - уязвимость в linux-5.10
In the Linux kernel, the following vulnerability has been resolved: iouring: prevents reg-wait speculation. By using ENTEREXTARGREG instead of passing a user pointer along with arguments for the waiting loop, the user can specify an offset within a pre-mapped region of memory. In this case, offse...
Astra Linux - уязвимость в linux-5.10, linux
In the Linux kernel, the following vulnerability has been resolved: x86/speculation: Fill RSB on vmexit for IBRS Prevent RSB underflow/poisoning attacks with RSB. Additionally, add a number of comments to attempt to document the current state of knowledge regarding RSB attacks and what exactly is...
Astra Linux - уязвимость в linux, linux-5.10
Certain Arm Cortex and Neoverse processors, as of 2022-03-08, do not properly prevent cache speculation, also known as Spectre-BHB. Attackers can exploit the shared branch history in the Branch History Buffer BHB to influence mispredicted branches. As a result, cache allocation may allow attacker...
Astra Linux - уязвимость в linux-5.10, linux-5.15
The Linux kernel allows user-space processes to enable mitigations by calling prctl with PRSETSPECULATIONCTRL, which disables the speculation feature, as well as through the use of seccomp. We noticed that on virtual machines of at least one major cloud provider, the kernel still left the victim...

CVE-2025-71203
CVE-2025-71203 concerns the Linux kernel where a user-controlled syscall number could be used to index the syscall table, enabling potential data leakage via cache side channels. The mitigation is to clamp the index with array_index_nospec() after the bounds check to prevent speculative out-of-bo...
