Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net: wwan: t7xx: Fixed the FSM command timeout issue When the driver processes the internal state change command, it uses an asynchronous thread to handle the command operation. If the main thread detects that the task has tim...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: wwan: t7xx: fix potential skb-frags overflow in the RX path When receiving data in the DPMAIF RX path, the t7xxdpmaifsetfragtoskb function adds page fragments to an skb without checking whether the number of fragments has...

CVE-2026-74263

A flaw was found in the Linux kernel's Wireless Wide Area Network WWAN t7xx driver. The t7xxportctrltx function, which handles control transmissions, fails to validate the return value of skbclone. An attacker with local access could exploit this by triggering a scenario where skbclone returns a...

Linux Distros Unpatched Vulnerability : CVE-2026-74263

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net: wwan: t7xx: check skbclone in control TX t7xxportctrltx clones each skb fragment before passing it to the port transmit path. The clone is used immediately...

Linux Distros Unpatched Vulnerability : CVE-2026-72059

CVE-2026-72059

A flaw was found in the Linux kernel's net: wwan: t7xx component. This issue occurs during the initialization of the Cellular Direct Memory Access CLDMA module. If the setup of the transmit or receive rings fails, a dedicated memory resource, known as a Direct Memory Access DMA pool, is not...

CVE-2026-74263

The CVE affects the Linux kernel net: wwan: t7xx driver. In t7xx_port_ctrl_tx, each skb fragment is cloned and the clone is immediately used to set cloned->len; if skb_clone() fails, a NULL pointer dereference can occur. The fix checks the clone before using it and, when previous fragments are...

CVE-2026-74263 net: wwan: t7xx: check skb_clone in control TX

In the Linux kernel, the following vulnerability has been resolved: net: wwan: t7xx: check skbclone in control TX t7xxportctrltx clones each skb fragment before passing it to the port transmit path. The clone is used immediately to set cloned-len, so an skbclone failure results in a NULL pointer...

CVE-2026-72059

Summary: The CVE-2026-72059 issue in the Linux kernel affects the wwan t7xx driver. During CLDMA late initialization, md_ctrl->gpd_dmapool is created before TX/RX rings are initialized. If a ring init fails, the code frees initialized rings but leaks the DMA pool. Consequence: potential DMA po...

CVE-2026-43495

A flaw was found in the Linux kernel, specifically within the net: wwan: t7xx module. A malicious modem could exploit this vulnerability by sending a specially crafted message with an invalid portcount value. This could lead to a slab-out-of-bounds read, potentially allowing an attacker to access...
