kernel: Linux kernel t7xx WWAN driver: Denial of Service via buffer overflow

A flaw was found in the Linux kernel's t7xx WWAN driver. A malicious, buggy, or compromised modem firmware can exploit this by sending packets with excessive fragments. This leads to a buffer overflow in the skbshinfoskb-frags array, corrupting adjacent memory. This can result in kernel crashes o...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: net: wwan: Fixed a global out-of-bounds read in wanrtnlpolicy. The variable wanrtnllinkops assigns a larger value to maxtype, leading to a global out-of-bounds read during the parsing of netlink attributes. This is exactly the...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: USB: wdm: the race between wdmopen and wdmwwanportstop has been eliminated. Clearing WDMWWANINUSE must be the last action; otherwise, we may open a device whose URBs User-Role-Based Services are still compromised...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net: wwan: t7xx: Fixed 64-bit access splitting to resolve alignment issues. Some registers are aligned at a 32-bit boundary, causing alignment errors on 64-bit platforms. Unable to handle kernel paging requests at the virtual...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: wwanhwsim: Fixed a possible memory leak in wwanhwsimdevnew. When a fault is injected while probing a module, if deviceregister fails, and the refcount of the kobject is not decreased to 0, the name allocated in devsetname may ...

In the Linux kernel, the following vulnerability has been resolved: net: wwan: t7xx: destroy DMA pool on CLDMA late init failure t7xxcldmalateinit creates mdctrl-gpddmapool before initializing the TX and RX rings. If any ring initialization fails, the error path frees the already initialized ring...

SUSE CVE-2026-72029

In the Linux kernel, the following vulnerability has been resolved: net: wwan: iosm: bound device offsets in the MUX downlink decoder muxdladbdecode walks a chain of aggregated datagram tables using offsets and lengths taken from the modem. firsttableindex, nexttableindex, tablelength,...

SUSE CVE-2026-74263

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...

The vulnerabilities of the functions ipc_imem_run_state_worker() (drivers/net/wwan/iosm/iosm_ipc_imem.c) and ipc_imem_wwan_channel_init() (drivers/net/wwan/iosm/iosm_ipc_imem_ops.c) of the Linux kernel’s network device drivers allow a attacker to cause a service failure.

The vulnerabilities of the functions ipcimemrunstateworker drivers/net/wwan/iosm/iosmipcimem.c and ipcimemwwanchannelinit drivers/net/wwan/iosm/iosmipcimemops.c of the Linux kernel’s network device drivers are related to the use of pointers. Exploiting these vulnerabilities could allow an attacke...
