CVE-2026-53228

A flaw was found in the Linux kernel's Simple Internet Transition SIT tunnel driver for IPv6. When processing network traffic with Generic Segmentation Offload GSO enabled, the driver may use a stale pointer to the inner IPv6 header after the socket buffer skb head has been reallocated. This can...

CVE-2026-53228

In the Linux kernel, the following vulnerability has been resolved: ipv6: sit: reload inner IPv6 header after GSO offloads ipip6tunnelxmit caches the inner IPv6 header pointer at function entry and continues using it after iptunnelhandleoffloads. For GSO skbs, iptunnelhandleoffloads calls...

CVE-2026-53091

A flaw was found in the Linux kernel's handling of Generic Segmentation Offload GSO packet headers. This vulnerability occurs when the qdiscpktlensegsinit function does not properly pull headers into the expected memory location, which can lead to incorrect processing by network drivers. A remote...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Net: Properly handles tunneled traffic when using GSO fallback for IPV6CSUM. NETIFFIPV6CSUM only indicates support for packet checksum offloading without IPv6 extension headers. Packets with extension headers must rely on...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: net: stmmac: fixed an issue where TSO DMA API usage caused errors. Commit 66600fac7a98 “net: stmmac: TSO: Fixed unbalanced DMA map/unmap for non-paged SKB data” corrected the assignment of members of txskbuffdma to a later...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: skbuff: Account for tail adjustment during pull operations Extending the tail of a data structure can have some unexpected side effects if a program uses a helper function like BPFFUNCskbpulldata to read partial content beyond th...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mptcp: handle large GSO sizes After the committed changes below, TCP sockets and MPTCP subflows can generate egress packets that are larger than 64K. This exceeds the maximum DSS data size; the packet length is misrepresented ove...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: gso: Fixed a panic that occurred when using a fraglist with mixed head allocation types. Since the commit 3dcbdb134f32 “net: gso: Fixed an error in skbsegment when splitting a gsosize mangled skb having linear-headed...
