In the Linux kernel, the following vulnerabilities have been resolved: ocfs2: fixed a memory leak in ocfs2stackglueinit The ocfs2tableheader should be freed in ocfs2stackglueinit if ocfs2sysfsinit fails; otherwise, kmemleak will report a memory leak. BUG: Memory leak Unreferenced object...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/exynos: vidi – fixed an issue to avoid directly dereferencing the user pointer. In vidiconnectionioctl, vidi-ediduser pointer is directly dereferenced in the kernel. This allows arbitrary kernel memory access from the user...

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...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: KEYS: Trusted – Fixed a memory leak in tpm2loadcmd. tpm2loadcmd allocates a temporary blob indirectly through tpm2keydecode, but the blob is not freed during failure paths. This issue can be addressed by wrapping the blob with a...

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, Linux 5.10

A guest can force the Linux netback driver to consume a large amount of kernel memory. This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVEs. Incoming data packets for a guest in the Linux kernel’s netback driver are buffere...

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 – Vulnerabilities in Linux 5.10, Linux 5.15

In multiple functions of iouring.c, there is a possibility of kernel memory corruption due to improper locking. This could lead to a local escalation of privileges in the kernel, as execution privileges are required. User interaction is not necessary for exploiting this vulnerability...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: vhost/vsock: Use kvmalloc/kvfree for larger packets. When copying a large file via sftp using vsock, the data size is usually 32 kB. In such cases, kmalloc seems to fail when attempting to allocate 32 32 kB regions. vhost-5837...

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

In the Linux kernel, the following vulnerability has been resolved: fbdev: omapfb: lcdmipid: Fixed an error handling path in mipidspiprobe. If ‘mipiddetect’ fails, we must free ‘md’ to avoid a memory leak...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the CAN BCM networking protocol within the Linux kernel. A local attacker can exploit this flaw in the CAN subsystem to corrupt memory, cause the system to crash, or escalate privileges. This race condition in the net/can/bcm.c file of the Linux kernel allows for local...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: mac80211: A potential double-free operation occurred during mesh join. While commit 6a01afcf8468 “mac80211: Mesh: Deleting ie data when leaving the mesh” fixed a memory leak that occurred during mesh leave/teardown, it introduced...

Astra Linux – Vulnerability in Linux, Linux 5.10

A vulnerability was discovered in the pfkeyregister function in the net/key/afkey.c file within the Linux kernel. This flaw allows a local, unprivileged user to gain access to kernel memory, resulting in a system crash or the leakage of internal kernel information...

Astra Linux – Vulnerability in Linux

The bpf verifier in the Linux kernel failed to properly handle truncation of the mod32 destination register when the source register was known to be 0. A local attacker who had the ability to load bpf programs could exploit this vulnerability by performing out-of-bounds reads in kernel memory,...
