CVE-2026-72036

A flaw was found in the Linux kernel's schmultiq component, which handles network packet scheduling. This vulnerability occurs when a non-work-conserving child queue is improperly handled after a packet has been temporarily stored. This can lead to a desynchronization of network packet queues and...

CVE-2026-72035

A flaw was found in the Linux kernel's taprio Time-Aware Priority Shaper scheduler. When the taprio software path processes network packets from a non-work-conserving child queue discipline qdisc, it can incorrectly handle the packet buffer, leading to a null pointer dereference. This issue can...

CVE-2026-72034

A flaw was found in the Linux kernel's file handle fhandle mechanism. A local attacker could exploit a vulnerability in the capablewrtmount function, which incorrectly handles detached mounts. By performing specific operations, an attacker could trigger a null pointer dereference, leading to a...

CVE-2026-72028

A flaw was found in the Linux kernel's kretprobe kernel return probe functionality on RISC-V architectures. A local attacker can trigger a kernel crash by attempting to read from the stack within a kretprobe. This occurs because the archrethooktrampoline does not correctly save the original stack...
