Astra Linux – Vulnerability in Linux

A issue was discovered in the Linux kernel through version 5.11.x. The kernel/bpf/verifier.c file contains unwanted out-of-bounds speculation during pointer arithmetic operations, which allows for side-channel attacks that circumvent Spectre mitigations and extract sensitive information from kern...

Astra Linux – Vulnerability in Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: x86/mm/identmap: Use GB pages only when a full GB page should be mapped. When identpudinit uses only GB pages to create identity maps, large ranges of addresses that are not actually requested can be included in the resulting...

Astra Linux – Vulnerability in Linux 5.10

An information leak flaw was discovered due to uninitialized memory in the Linux kernel’s TIPC protocol subsystem, during the process of a user sending a TIPC datagram to one or more destinations. This flaw allows a local user to read certain parts of the kernel’s memory. The affected data is no...

Astra Linux – Vulnerability in 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. This occurs because a certain preempting store operation does not necessarily occur before a store operation whose valu...

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

KGDB and KDB allow read and write access to kernel memory, and therefore should be restricted during lockdown. An attacker with access to a serial port could trigger the debugger, so it is important that the debugger respects the lockdown mode when/if it is triggered. CVSS 3.1 Base Score: 6.7...
