Astra Linux – Vulnerability in Qemu

A race condition flaw was discovered in the 9pfs server implementation of QEMU, up to and including version 5.2.0. This flaw allows a malicious 9p client to cause a use-after-free error, potentially escalating their privileges on the system. The greatest threat posed by this vulnerability is to...

Astra Linux – Vulnerability in Qemu

QEMU prior to version 8.2.0 has an integer underflow issue, which can lead to a buffer overflow. This occurs due to a TI command, where a transfer length that is not a DMA transfer is processed, even though that length is shorter than the length of the available FIFO data. This issue arises in th...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QXL display device emulation in QEMU. The double retrieval of the guest-controlled values cursor-header.width and cursor-header.height can lead to the allocation of a small cursor object, followed by a subsequent heap-based buffer overflow. A malicious privileged gues...

Astra Linux – Vulnerability in Qemu

An infinite loop flaw was discovered in the e1000 NIC emulator of QEMU. This issue occurs when processing transmit tx descriptors in processtxdesc, especially if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host, resulting in...

Astra Linux – Vulnerability in Qemu

In QEMU 5.0.0, the hw/usb/hcd-ohci.c file contains an infinite loop when a TD list has a loop...

Astra Linux – Vulnerability in Qemu

A NULL pointer dereference flaw was discovered in the floppy disk emulator of QEMU. This issue occurs when processing read/write ioport commands, especially if the selected floppy drive is not initialized using a block device. This flaw allows a privileged guest user to crash the QEMU process on...

Astra Linux – Vulnerability in Qemu

A use-after-free flaw was discovered in the MegaRAID emulator of QEMU. This issue occurs during the processing of SCSI I/O requests when the mptsasfreerequest function fails to dequeue the request object ‘req’ from the pending requests queue. This flaw allows a privileged guest user to crash the...

Astra Linux – Vulnerability in Qemu

In QEMU 5.0.0, the file hw/net/e1000ecore.c contains an infinite loop that occurs due to a NULL buffer address in the RX descriptor...

Astra Linux – Vulnerability in Qemu

In QEMU, the softmmu/physmem.c file, versions up to 7.0.0, can perform an uninitialized read on the translatefail path, resulting in an ioreadx or iowritex crash. NOTE: A third-party report states that the “Non-virtualization Use Case” described in the qemu.org reference applies here. In other...

CVE-2026-45038

Tabby formerly Terminus is a highly configurable terminal emulator. Prior to 1.0.233, since Tabby does not escape control characters from file paths when dragging and dropping a file into it, code execution can be achieved. This vulnerability is fixed in 1.0.233...

CVE-2026-45038 Tabby: Dragging and Dropping a File into Tabby Can Lead to Code Execution

Tabby formerly Terminus is a highly configurable terminal emulator. Prior to 1.0.233, since Tabby does not escape control characters from file paths when dragging and dropping a file into it, code execution can be achieved. This vulnerability is fixed in 1.0.233...

CVE-2026-45036 Tabby auto-confirms ZMODEM detection on terminal output, leading to shell command execution from displayed file content under fish, bash, and zsh

Tabby formerly Terminus is a highly configurable terminal emulator. Prior to 1.0.233, Tabby before 1.0.233 automatically confirms ZMODEM protocol detection on all terminal session output without user interaction, enabling shell command execution when a user displays attacker-controlled content. T...

CVE-2026-45036

Summary of CVE-2026-45036 : Tabby (formerly Terminus) before version 1.0.233 may automatically confirm ZMODEM protocol detection on terminal output via ZModemMiddleware, writing a fixed ZRINIT response back into the active PTY. This leads to injected bytes being consumed by the user’s shell as co...

The vulnerability of the QEMU hardware emulation software, which allows a hacker to trigger a service failure

The vulnerability of the QEMU hardware emulation software is related to the allocation of unlimited memory. Exploiting this vulnerability can allow a hacker to cause a system failure...

The vulnerability of the emulator library for the VTE terminal, which allows a hacker to trigger a service failure

The vulnerability of the terminal emulation library VTE is related to an uncontrolled resource consumption. Exploiting this vulnerability can allow a hacker to cause a service failure...

OESA-2026-2091 qemu security update

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fixes: A flaw was found in QEMU. A specially crafted VMDK image could trigger an out-of-bounds read vulnerability, potentially leading to a 12-byte leak of sensitive information or a denial of...

PT-2026-34940

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free issue exists in the KVM x86 component.
