CVE-2026-80844

Linux kernel IPsec AH6 transformation is vulnerable to an out-of-bounds memory access via a crafted IPv6 Routing Header. The function ipv6_rearrange_rthdr() assumes the segments_left field does not exceed the number of addresses implied by hdrlen. For raw IPv6 HDRINCL packets this invariant is no...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net: ipv6: Fixed warnings related to memcpy operations that span multiple fields in the AH output. These warnings occur when extension headers are copied to IPv6 address fields, causing Fortify-string warnings regarding writes...

The vulnerability of the functions ah6_output_done() and ah6_output() in the Linux kernel’s net/ipv6/ah6.c file allows a attacker to cause a service failure.

The vulnerability of the functions ah6outputdone and ah6output in the Linux kernel’s net/ipv6/ah6.c file is related to incorrect calculation of buffer size. Exploiting this vulnerability could allow an attacker to cause a service failure...
