Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In 64-bit versions of the Linux kernel, Copyfromuser does not implement uaccessbeginnospec, which allows a user to bypass the “accessok” check and pass a kernel pointer to copyfromuser. This would enable an attacker to leak sensitive information. We recommend upgrading beyond commit...

PT-2026-72694

In the Linux kernel, the following vulnerability has been resolved: bpf: Guard get user acesss with access ok for uprobe multi data As reported by sashiko 1 we need to use access ok to check the user space data bounds before we use get-user to get it. 1...

The vulnerability of the __access_ok() function in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the accessok function in the Linux operating system’s kernel is related to incorrect comparisons. Exploiting this vulnerability could allow a remote attacker to cause service interruptions...

CVE-2022-50080 tee: add overflow check in register_shm_helper()

In the Linux kernel, the following vulnerability has been resolved: tee: add overflow check in registershmhelper With special lengths supplied by user space, registershmhelper has an integer overflow when calculating the number of pages covered by a supplied user space memory region. This causes...

SUSE CVE-2022-49289

In the Linux kernel, the following vulnerability has been resolved: uaccess: fix integer overflow on accessok Three architectures check the end of a user access against the address limit without taking a possible overflow into account. Passing a negative length or another overflow in here returns...

kernel: Copy_from_user on 64-bit versions may leak kernel information

A vulnerability was found in copyfromuser in 64-bit versions of the Linux kernel. This flaw allows a local attacker to bypass the "accessok" sanity check and pass a kernel pointer to copyfromuser, resulting in kernel data leaking...
