In the Linux kernel, the following vulnerability has been resolved: batman-adv: mcast: linearize skbuff for packet generation batadvmcastforwpacket and batadvmcastforwscrape is not only called indirectly by the unsharing+linearizing batadvrecvmcastpacket handler. When it is called indirectly by...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerabilities have been resolved: tipc: A possible memory leak has been fixed in tipcbufAppend. The function skblinearize does not free the skb when it fails. Therefore, move /buf = NULL/ after skblinearize, so that the skb can be freed in case of an error...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Fixed a panic that occurred when calling skblinearize. The panic can be reproduced by executing the command: ./bench sockmap -c 2 -p 1 -a --rx-verdict-ingress --rx-strp 100000 A kernel panic was then captured: '''...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: BPF, sockmap: Fixed a potential memory leak in an unlikely error case. If the skblinearize function is required and fails, we might leak a message during error handling. To address this issue, we ensure that we free the message...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: virtio-net: Ensure that the received length does not exceed the allocated size. In xdplinearizepage, when reading the following buffers from the ring, we forget to check the received length against the actual allocated size. This...

CVE-2026-72228 batman-adv: frag: fix primary_if leak on failed linearization

In the Linux kernel, the following vulnerability has been resolved: batman-adv: frag: fix primaryif leak on failed linearization If the skb has a fraglist, it must be linearized before it can be split using skbsplit. But when this step failed, it must not only free the skb but also take care of t...

CVE-2026-10665 Heap buffer overflow on WireGuard receive path via unbounded incoming packet length

In Zephyr's WireGuard subsystem subsys/net/lib/wireguard, wgprocessdatamessage in wgcrypto.c linearizes an inbound transport-data payload into a fixed pool buffer of CONFIGWIREGUARDBUFLEN bytes before decryption. The call netbuflinearizebuf-data, datalen, pkt-buffer, ..., datalen passed the...

PT-2026-57567

Name of the Vulnerable Software and Affected Versions Zephyr version 4.4.0 Description An out-of-bounds write exists in the WireGuard subsystem within the wg process data message function located in wg crypto.c. The issue occurs when an inbound transport-data payload is linearized into a fixed po...
