CVE-2026-43450 is an out-of-bounds read vulnerability in the Linux kernel Netfilter nfnetlink_cthelper component's nfnl_cthelper_dump_table() function. If the connection-tracking helper saved in cb->args[1] is deleted between dump rounds, the saved pointer remains uncleared and traversal can finish with cb->args[0] equal to nf_ct_helper_hsize. A misplaced 'goto restart' then jumps into the loop body without rechecking its bounds, causing an eight-byte read beyond the helper hash table. The fix moves the restart block inside the for-loop body, ensuring that traversal restarts only while the bucket index remains valid.

An out-of-bounds read in the Linux kernel Netfilter function nfnl_cthelper_dump_table(). The plugin attributes a CVSS v3 base score of 7.1 to this vulnerability, with local access, low privileges, and high confidentiality and availability impacts.
A Linux kernel Netfilter vulnerability in nfnl_cthelper_dump_table() permits an 8-byte out-of-bounds read when a saved connection-tracking helper is deleted between dump rounds. Incorrect placement of a restart block allows execution to bypass the hash-table bounds check. The listed CVSS v3 score is 7.1, with local access, low privileges, and high confidentiality and availability impacts. The fix moves the restart block inside the loop to preserve bounds checking.
An out-of-bounds read vulnerability in the Linux kernel's Netfilter connection-tracking helper dump function. Deleting a saved helper between dump rounds can cause a restart to bypass the hash-table bounds check. The fix moves the restart block inside the loop. The reference assigns CVSS v3 severity 7.1, indicating local exploitation requiring low privileges, with potential high confidentiality and availability impacts.
A Linux kernel Netfilter vulnerability in nfnl_cthelper_dump_table() causes an 8-byte out-of-bounds read when a saved connection-tracking helper is deleted between dump rounds. Incorrect restart logic jumps into the loop body after the bucket index reaches the hash-table limit. The advisory assigns CVSS v3 severity High (7.1), with local access and low privileges required and potential confidentiality and availability impacts. The fix moves the restart block inside the loop to preserve bounds checking.
