CVE-2026-97417

Name of the Vulnerable Software and Affected Versions Linux Kernel (affected versions not specified)

Description An issue exists in the netfilter nf conntrack component within the tcp sack() function. The timestamp-only fast path incorrectly dereferences the option stream as a 4-byte aligned pointer, which the TCP option stream does not guarantee. This can lead to memory access issues when the data is not properly aligned.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
