CVE-2026-97961

The Linux kernel contains a vulnerability in the perf/core subsystem where a list corruption can occur. The issue arises because the function perf_sched_cb_dec() may attempt to remove an entry from the sched_cb_list while that list node is still in use by perf_pmu_sched_task(). This specific path...

CVE-2026-97960 perf/x86/intel: Prevent drain_pebs() reentry

In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel: Prevent drainpebs reentry The PEBS buffer is shared by all events on a CPU, so drainpebs must not be reentered. If so, one instance may observe stale buffer state and potentially access out-of-bound memory. Most...

CVE-2026-97959

The Linux kernel contains a memory leak vulnerability in the net/sched: cls_route component. When an existing filter is moved to a different top-level bucket via route4_change, the filter is unlinked from the old bucket, but the bucket is never freed. This results in stale empty buckets remaining...

CVE-2026-97959 net/sched: cls_route: free emptied bucket on filter move

In the Linux kernel, the following vulnerability has been resolved: net/sched: clsroute: free emptied bucket on filter move route4change can move an existing filter to a different top-level bucket: route4setparms recomputes the handle from TCAROUTE4TO/ FROM/IIF, and the handle-mismatch check is...

CVE-2026-97960

The Linux kernel is vulnerable to a reentry issue in the perf/x86/intel component. The PEBS buffer is shared by all events on a CPU, meaning drain_pebs() must not be reentered; otherwise, an instance might observe a stale buffer state and potentially access out-of-bound memory . While most calls ...

CVE-2026-97958 net/sched: cls_api: Don't replay RTM_GETCHAIN in tc_ctl_chain().

In the Linux kernel, the following vulnerability has been resolved: net/sched: clsapi: Don't replay RTMGETCHAIN in tcctlchain. If a netlink socket sends RTMGETCHAIN requests repeatedly without recving the responses, tcctlchain hogs CPU and triggers Hung Task splat. 0 As caught in the stack trace,...

CVE-2026-97957 net: hinic: fix mailbox segment buffer overflow

In the Linux kernel, the following vulnerability has been resolved: net: hinic: fix mailbox segment buffer overflow checkmboxseqidandseglen validates that seqid does not exceed SEQIDMAXVAL 42 and seglen does not exceed MBOXSEGLEN 48. However, this allows the last segment seqid=42 to carry a full...

However, this allows the last segment seqid=42 to carry a full...

CVE-2026-97957

The Linux kernel contains a heap buffer overflow vulnerability within the hinic driver. The issue originates in the check_mbox_seq_id_and_seg_len() function, which fails to account for the remaining buffer space when processing the last segment. Specifically, it allows a segment with seq_id=42 to...

In the Linux kernel, the following vulnerability has been resolved: net/sched: clsapi: Don't replay RTMGETCHAIN in tcctlchain. If a netlink socket sends RTMGETCHAIN requests repeatedly without recving the responses, tcctlchain hogs CPU and triggers Hung Task splat. 0 As caught in the stack trace,...

CVE-2026-97958

The Linux kernel is vulnerable to a CPU hogging issue in net/sched: cls_api due to how tc_ctl_chain() handles repeated RTM_GETCHAIN requests. If a netlink socket sends these requests without consuming the responses, netlink_attachskb() may return -EAGAIN when the receive buffer is full, causing t...
