kernel: Linux kernel KVM: Privilege escalation or denial of service due to improper shadow page table entry handling

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. A local attacker with privileges on the host system could exploit a vulnerability in how KVM handles shadow page table entries SPTEs during memory-mapped I/O MMIO operations. By manipulating guest page table entrie...

kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged...

CVE-2026-44933

A flaw was found in libzypp. This vulnerability allows a local attacker to bypass security restrictions within the PluginScript component. By exploiting how the system attempts to isolate plugins, an attacker can execute unauthorized programs on the host system with root privileges...

CVE-2026-42834

Improper access control in Windows Admin Center allows an authorized attacker to elevate privileges over a network...

Astra Linux – Vulnerability in Linux

A vulnerability was discovered in aspeedlpcctrlmmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c in the Linux kernel before version 5.14.6. Local attackers who had access to the Aspeed LPC control interface could overwrite memory in the kernel and potentially execute privileged operations, denoted as...

Astra Linux – Vulnerability in ffmpeg, ffmpeg5

A buffer overflow vulnerability exists in Ffmpeg v.n6.1-3-g466799d4f5, allowing a local attacker to execute arbitrary code through the ffbwdiffilterintrac function in the libavfilter/bwdifdsp.c:125:5 component...

Astra Linux – Vulnerability in Linux, Linux 5.10

A use-after-free vulnerability was discovered in the rtsxusbmsdrvremove function in the drivers/memstick/host/rtsxusbms.c file within the memstick module of the Linux kernel. In this flaw, a local attacker with user privileges could compromise the confidentiality of system resources. This...

Astra Linux – Vulnerability in Chromium

Inappropriate implementations of Skia in Google Chrome prior to version 88.0.4324.146 allowed a local attacker to spoof the contents of the Omnibox URL bar through a crafted HTML page...

Astra Linux – Vulnerability in Thunderbird

Signatures are written to disk before and read during verification. This may lead to a race condition if a malicious local process or user replaces the file. This vulnerability affects Thunderbird 78.10...

Astra Linux – Vulnerability in ffmpeg5

FFmpeg v.n6.1-3-g466799d4f5 allows an attacker to trigger the use of a parameter with a negative value in the avsamplessetsilence function located at line 260:9 in the libavutil/samplefmt.c component...

Astra Linux – Vulnerability in GhostScript

A buffer overflow vulnerability was discovered in base/gdevdevn.c:1973 within devnpcxwriterle in ghostscript. This issue may allow a local attacker to cause a denial of service by generating a malicious PDF file for a DEVN device using gs...

Astra Linux – Vulnerability in Python 3.7

There is a flaw in Python 3’s pydoc documentation. A local or nearby attacker who discovers or can convince another local or nearby user to start a pydoc server could access the server and use it to disclose sensitive information belonging to that user that they would not normally be able to...

Astra Linux – Vulnerability in Linux 5.10, Linux

A NULL pointer dereference flaw exists in the diFree function in the fs/jfs/inode.c file of the Journaled File System JFS in the Linux kernel. This flaw could allow a local attacker to crash the system or leak internal kernel information...

Astra Linux – Vulnerability in Systemd

It was discovered that a Systemd service that uses the DynamicUser property can create a SUID/SGID binary that will be allowed to run as the transient service’s UID/GID even after the service is terminated. A local attacker could exploit this flaw to access resources that will be owned by a...

Astra Linux – Vulnerability in Linux

Linux Kernel Bluetooth CMTP Module Double Free Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of the Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in orde...

Astra Linux – Vulnerability in Linux, Linux 5.10

A data leak flaw was discovered in the way of the XFSIOCALLOCSP IOCTL in the XFS filesystem, which allows for an increase in file sizes when the size is unaligned. A local attacker could exploit this flaw to leak data from the XFS filesystem that would otherwise be inaccessible to them...

Astra Linux – Vulnerability in Linux

An out-of-bounds memory access flaw was discovered in the fs/f2fs/node.c file within the f2fs module of the Linux kernel, in versions prior to 5.12.0-rc4. A failure in the bounds check allows a local attacker to gain access to out-of-bounds memory, resulting in a system crash or the leakage of...
