DEBIAN-CVE-2026-98850
In the Linux kernel, the following vulnerability has been resolved: net/packet: prevent TXRING byte count overflow tpacketsnd drains every SENDREQUEST frame in a TX ring and adds each valid packet length to the signed int lensum. Userspace can recycle completed frames concurrently, so a single...
AZL-108632 CVE-2026-98503 affecting package kernel 6.6.159.1-1
In the Linux kernel, the following vulnerability has been resolved: packet: use ubufinfo completion for TXRING packets tpacketsnd sends skbs with frags pointing into its ring slots. Slots are released when skb-destructor is called. A call to skborphan calls skb-destructor before the skb is freed...

Linux Kernel Security Vulnerabilities
The Linux kernel version 2.6.31 contains a security vulnerability. This vulnerability arises from the tpacketsnd function, which, when processing SENDREQUEST frames of the TX ring, accumulates the length of valid packets into the symbolic integer lensum. This process does not prevent an overflow ...
CVE-2026-98503: Undefined Security Weakness
In the Linux kernel, the following vulnerability has been resolved: packet: use ubufinfo completion for TXRING packets tpacketsnd sends skbs with frags pointing into its ring slots. Slots are released when skb-destructor is called. A call to skborphan calls skb-destructor before the skb is freed...
Linux Kernel Security Vulnerabilities
There are security vulnerabilities in Linux kernels versions from 4.14.86 to 4.15, as well as versions from 4.19.7 to 4.20, and 4.20 itself. These vulnerabilities arise when the tpacketsnd function sends skb fragments to ring buffer slots, causing skborphan to call skb-destructor before the skb i...
Astra Linux – vulnerability in linux-5.10, linux-6.1
In the Linux kernel, the following vulnerability has been resolved: packet: use consistent hardheaderlen in TXRING send path tpacketsnd reads dev-hardheaderlen independently for skb allocation and header construction in tpacketfillskb. Concurrent netdevice reconfiguration can therefore make the...
ROS-20260918-73-0037
The vulnerability of the tpacketsnd function in the net/packet/afpacket.c module of the Linux kernel is related to synchronization errors when using shared resources „Race Conditions“. Exploiting this vulnerability can allow an attacker to compromise the confidentiality, integrity, and...
