CVE-2026-46274

In the Linux kernel vulnerability CVE-2026-46274, the issue lies in the work-queue (io-wq) hash handling: io_wq_remove_pending() could leave a dangling pointer in wq->hash_tail[0] when a hashed bucket-0 work is canceled with a non-hashed predecessor. The root cause was that io_get_work_hash() ...

EUVD-2026-35078

In the Linux kernel, the following vulnerability has been resolved: io-wq: check that the predecessor is hashed in iowqremovepending iowqremovepending needs to fix up wq-hashtail if the cancelled work was the tail of its hash bucket. When doing this, it checks whether the preceding entry in...

CVE-2026-46274 io-wq: check that the predecessor is hashed in io_wq_remove_pending()

In the Linux kernel, the following vulnerability has been resolved: io-wq: check that the predecessor is hashed in iowqremovepending iowqremovepending needs to fix up wq-hashtail if the cancelled work was the tail of its hash bucket. When doing this, it checks whether the preceding entry in...

CVE-2025-71315

The CVE-2025-71315 entry describes a Linux kernel fix: the vkms vblank timer is replaced by the DRM vblank timer implementation, removing vkms’ hrtimer and routing through vkms’ handle_vblank_timeout via drm_crtc_helper_funcs. This clarifies the affected component as the vkms driver in the DRM su...

EUVD-2025-210081

In the Linux kernel, the following vulnerability has been resolved: drm/vkms: Convert to DRM's vblank timer Replace vkms' vblank timer with the DRM implementation. The DRM code is identical in concept, but differs in implementation. Vblank timers are covered in vblank helpers and initializer...

kernel: smb: client: fix OOB reads parsing symlink error response

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote, untrusted server could send a specially crafted symlink error response, leading to an out-of-bounds read vulnerability. This could result in the disclosure of sensitive information from the kernel's memory to a loca...

Important: Red Hat Security Advisory: kernel security update

An update for kernel is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from th...

kernel: Linux kernel: smb: client: reject userspace cifs.spnego descriptions

A privilege escalation vulnerability was found in the Linux kernel's CIFS client implementation. This could allow a local attacker to impersonate other users, bypass authentication in SMB mount operations, and potentially gain unauthorized access to network file shares or escalate privileges...

kernel: usbip: validate number_of_packets in usbip_pack_ret_submit()

A flaw was found in the Linux kernel's USB/IP subsystem. A malicious USB/IP server could exploit a vulnerability in the usbippackretsubmit function by sending a specially crafted RETSUBMIT response. This response, containing an oversized numberofpackets value, could cause a heap out-of-bounds...

kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()

A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option CIPSO IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 IC...

kernel: netfilter: ip6t_eui64: reject invalid MAC header for all packets

A flaw was found in the Linux kernel's netfilter component. This vulnerability occurs because the eui64mt6 function, which processes IPv6 packets, does not properly validate the MAC header for all packets. Specifically, packets with a zero fragment offset could bypass an existing guard, allowing...

kernel: Linux kernel: Use-after-free in traffic control (act_ct) may lead to denial of service or privilege escalation

A flaw was found in the Linux kernel. A use-after-free vulnerability exists in the traffic control actct path when it is incorrectly configured with non-ingress egress qdiscs queueing disciplines. This can allow a local user with specific privileges to trigger a kernel crash, leading to a denial ...

kernel: netfilter: nf_tables: release flowtable after rcu grace period on error

A flaw was found in the Linux kernel's netfilter component, specifically within the nftables subsystem. An error in releasing a flowtable after an RCU Read-Copy-Update grace period could lead to a use-after-free vulnerability. This issue could expose the flowtable to the packet path and...
