Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: RISCV: Fixed TASKSIZE on 64-bit NOMMU. On NOMMU, user space memory can originate from anywhere within physical RAM. The current definition of TASKSIZE is incorrect if any RAM exceeds 4GB, causing spurious failures in user space...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: EFI: In runtime mode, a potential overflow of the size of the soft-reserved region has been fixed. If there are pages worth ≥ 4GB in a soft-reserved region, the value of mdsize will be reduced...

CVE-2026-16280

An integer overflow when calculating physical offsets for sparse PMRs may result in 32-bit truncation of address computations for PMRs larger than 4 GB. This can lead to incorrect GPU MMU mappings and may allow a non-privileged user to trigger access to unintended physical memory, resulting in...

CVE-2026-53015

A flaw was found in the Linux kernel's erofs filesystem. On 32-bit platforms, the lcn variable, used for logical cluster numbers, was defined as a 32-bit integer. This could lead to truncation when calculating offsets larger than 4 Gigabytes GiB, potentially causing incorrect data handling within...

CVE-2026-55967

AES-GCM encryption/decryption with extremely large cumulative single message sizes 64 GiB were not properly rejected by the streaming APIs, allowing counter wrap, keystream reuse, and consequent plaintext recovery...

CVE-2026-55967 AES-GCM streaming APIs do not reject >64 GiB cumulative single messages, enabling counter wrap and keystream reuse

AES-GCM encryption/decryption with extremely large cumulative single message sizes 64 GiB were not properly rejected by the streaming APIs, allowing counter wrap, keystream reuse, and consequent plaintext recovery...

CVE-2026-53133

In the Linux kernel, the following vulnerability has been resolved: RDMA/umem: Fix truncation for block sizes = 4G When the iommu is used the linearization of the mapping can give a single block that is very large split across multiple SG entries. When rdmablockiternext reassembles the split SG...

CVE-2023-29146

The utility functions used by Malwarebytes EDR 1.0.11 on Linux for calculating a cryptographic hash of data bytes truncate the hashed data if it exceeds 4GB. This leads to an integer wrap-around if the data is larger than the maximum unsigned integer value 32-bit. Attackers could create a collidi...

CVE-2026-39834

A flaw was found in golang.org/x/crypto/ssh. When a remote attacker attempts to write data larger than 4GB in a single call on an SSH Secure Shell channel, an integer overflow occurs in the internal payload size calculation. This vulnerability causes the write loop to spin indefinitely,...

CVE-2026-5477

An integer overflow existed in the wolfCrypt CMAC implementation, that could be exploited to forge CMAC tags. The function wcCmacUpdate used the guard if cmac-totalSz != 0 to skip XOR-chaining on the first block where digest is all-zeros and the XOR is a no-op. However, totalSz is word32 and wrap...
