CVE-2026-68286

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

Description An issue exists in the drop monitor component where u64 stats update begin(), u64 stats inc(), and u64 stats update end() are called after spin unlock irqrestore(), allowing local interrupts to be re-enabled. On 32-bit architectures, u64 stats update begin() disables preemption but not interrupts. If a nested interrupt occurs on the same CPU during a 64-bit stats update within the net dm packet trace kfree skb hit() and net dm hw trap packet probe() functions, the reentrant seqcount update can corrupt the stats value or the seqcount state.

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