CVE-2026-43916
HighSummary
The PAM session module pam_authnft, which binds nftables firewall rules to authenticated sessions, had a vulnerability related to heap buffer over-reads in versions prior to 0.2.0-alpha. This allowed a crafted NETLINK_SOCK_DIAG reply to bypass the message-size check, leading to dereferencing past the end of the allocation.
Risk Assessment
This vulnerability could lead to unauthorized memory access, posing a risk of data leakage or system instability. Organizations should be aware of the potential threats associated with the exploitation of this flaw.
Recommendation
It is recommended to upgrade to version 0.2.0-alpha or later to mitigate this vulnerability. Regular monitoring and updating of system components is crucial for maintaining security.

Original NVD description (English source)
pam_authnft is a PAM session module binding nftables firewall rules to authenticated sessions via cgroupv2 inodes. Prior to 0.2.0-alpha, a heap buffer over-read in peer_lookup_tcp (src/peer_lookup.c:134, prior to the fix) allowed a crafted NETLINK_SOCK_DIAG reply to slip past the message-size check, then dereference past the end of the allocation. This vulnerability is fixed in 0.2.0-alpha.
