The vulnerability exists due to incorrect sequence-number accounting in the Linux kernel BPF sockmap component when a BPF stream_verdict program redirects data back to the same socket with BPF_F_INGRESS. A local privileged user can trigger this self-redirect followed by a socket read to advance copied_seq twice for the same data, triggering kernel warnings and potentially disrupting TCP receive processing.

2937) NULL pointer dereference (CVE-ID: CVE-2026-98926)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a null pointer dereference in the Linux kernel AMD display driver's link_set_dpms_on() and link_set_dpms_off() functions when processing display power-management transitions without a stream sink. A local user can trigger affected operations while stream->sink is null to potentially cause a kernel crash and denial of service.

2938) Use-after-free (CVE-ID: CVE-2026-98927)

CWE-ID: CWE-416 - Use After Free

CVSSv4: 5.7 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local user to potentially cause a denial of service through a kernel crash.

The vulnerability exists due to use-after-free in the Linux kernel arm64 KVM nested virtualization component when VCPU_INIT relocates the nested_mmus array while a vCPU is running an L2 guest. A local user can trigger concurrent vCPU initialization and nested guest execution to potentially cause a denial of service by leaving the running vCPU accessing a freed shadow page table structure.

2939) NULL pointer dereference (CVE-ID: CVE-2026-98928)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local privileged user to cause a denial of service through a NULL pointer dereference in the hypervisor.

The vulnerability exists due to inconsistent validation of SVE feature indicators in the arm64 KVM function pkvm_init_features_from_host() when initializing guest CPU features from host-supplied state. A local privileged user can set KVM_ARCH_FLAG_GUEST_HAS_SVE without setting KVM_ARM_VCPU_SVE, causing the world switch to load guest SVE state through a NULL sve_state pointer and potentially crash the hypervisor.

2940) Use of uninitialized resource (CVE-ID: CVE-2026-98929)

CWE-ID: CWE-908 - Use of Uninitialized Resource

CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]

The vulnerability allows a local privileged user to trigger a kernel warning and cause MACsec registration notifications to report uninitialized security attributes.

The vulnerability exists due to use of an uninitialized resource in the Linux kernel MACsec driver when network device registration generates notifications before the security entity (SecY) is initialized. A local privileged user can create a MACsec device to cause notifications to report uninitialized SecY attributes, including the secure channel identifier (SCI). Creating the device with MAC offload over an LRO-capable lower device while IPv4 forwarding is enabled by default also triggers a warning in rtmsg_ifinfo_build_skb(), because macsec_fill_info() encounters a zero key_len and returns -EMSGSIZE.

2941) Improper locking (CVE-ID: CVE-2026-98930)

CWE-ID: CWE-667 - Improper Locking

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local user to potentially cause a denial of service.

The vulnerability exists due to improper locking in the Linux kernel's s390 KVM interrupt handling when processing a SIGP Stop and Store Status operation for an already stopped vCPU. A local user can trigger a status-store operation that writes to userspace while a spinlock is held, allowing a page fault to require blocking in an atomic context and potentially cause a denial of service.
