Astra Linux – Vulnerability in Qemu

A “off-by-one” read/write issue was identified in the SDHCI device of QEMU. This issue occurs when reading/writing the Buffer Data Port Register using the sdhcireaddataport and sdhciwritedataport functions, specifically when datacount == blocksize. A malicious guest could exploit this flaw to cra...

Astra Linux – Vulnerability in Qemu

A vulnerability related to out-of-bounds read/write access was discovered in the USB emulator of QEMU in versions prior to 5.2.0. This issue occurs during the processing of USB packets from a guest, when the value of USBDevice’s ‘setuplen’ exceeds the value of ‘databuf4096’ in the dotokenin and...

Astra Linux – Vulnerability in Qemu

In QEMU 5.0.0, the file hw/usb/hcd-ohci.c contains a stack-based buffer over-read issue, caused by values obtained from the host controller driver...

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 libslirp

An invalid pointer initialization issue was discovered in the SLiRP networking implementation of QEMU. The flaw resides in the tftpinput function and can occur when processing an UDP packet that is smaller than the size of the ‘tftpt’ structure. This issue may lead to out-of-bounds read access or...

Astra Linux – Vulnerability in Qemu

A heap buffer overflow was discovered in the floppy disk emulator of QEMU up to version 6.0.0 inclusive. This issue could occur in the fdctrltransferhandler function in the hw/block/fdc.c file, during the processing of DMA read data transfers from the floppy drive to the guest system. A privilege...

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

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...

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

A issue was discovered in QEMU through version 5.1.0. An out-of-bounds memory access was identified in the ATI VGA device implementation. This flaw occurs in the ati2dblt routine in hw/display/ati2d.c, during handling of MMIO write operations via the atimmwrite callback. A malicious guest could...

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

The ethgetgsotype function in net/eth.c in QEMU 4.2.1 allows guest OS users to trigger an assertion failure. A guest can crash the QEMU process by sending packet data that lacks a valid Layer 3 protocol...

Astra Linux – Vulnerability in Qemu

In QEMU 5.1.0, the ideatapicmdreplyend variable in hw/ide/atapi.c allows out-of-bounds read access, as the buffer index is not validated...

Astra Linux – Vulnerability in Qemu

An integer overflow issue was identified in the vmxnet3 NIC emulator of QEMU for versions up to v5.2.0. This issue can occur if a guest provides invalid values for the rx/tx queue size or other NIC parameters. A privileged guest user may exploit this flaw to crash the QEMU process on the host,...

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...

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...
