CVE-2026-63927

A flaw was found in the Linux kernel, specifically within the dwc2 USB driver. This vulnerability, known as a use-after-free, occurs when the system attempts to access memory that has already been released. This happens because a USB Request Block urb is incorrectly accessed after it has been...

CVE-2026-64071 nvme-pci: fix use-after-free in nvme_free_host_mem()

In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fix use-after-free in nvmefreehostmem nvmefreehostmem frees dev-hmbsgt via dmafreenoncontiguous but never clears the pointer afterward. This leads to a use-after-free if nvmefreehostmem is called twice in the same error...

JLSEC-2026-725 A heap use-after-free exists in wolfSSL's TLS 1.3 post-quantum cryptography (PQC) hybrid KeyShare...

A heap use-after-free exists in wolfSSL's TLS 1.3 post-quantum cryptography PQC hybrid KeyShare processing. In the error handling path of TLSXKeyShareProcessPqcHybridClient in src/tls.c, the inner function TLSXKeyShareProcessPqcClientex frees a KyberKey object upon encountering an error. The call...

The vulnerability of the `vidtv_channel_si_init()` function in the `drivers/media/test-drivers/vidtv/vidtv_channel.c` file of the Linux kernel-based multimedia device driver allows a remote attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the vidtvchannelsiinit function in the drivers/media/test-drivers/vidtv/vidtvchannel.c file of the Linux kernel multimedia device driver relates to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the...

The vulnerability of the ets_qdisc_change() function in the net/sched/sch_ets.c module of the network/sched/sch_ets.c subsystem of the Linux operating system’s networking subsystem allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the etsqdiscchange function in the net/sched/schets.c file, within the network scheduling subsystem of the Linux kernel, is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality,...

Name of the Vulnerable Software and Affected Versions The product name cannot be determined affected versions not specified Description Memory corruption occurs when processing multiple IOCTL Input/Output Control calls that use the same buffer file descriptor input. This issue is caused by a...

The vulnerability of the cros_ec_ishtp_remove() function in the drivers/platform/chrome/cros_ec_ishtp.c module of the Chrome OS device support module for Linux kernel allows a malicious actor to cause a service failure.

The vulnerability of the crosecishtpremove function in the drivers/platform/chrome/crosecishtp.c module of the Chrome OS device driver support module is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2026-53228

A flaw was found in the Linux kernel's Simple Internet Transition SIT tunnel driver for IPv6. When processing network traffic with Generic Segmentation Offload GSO enabled, the driver may use a stale pointer to the inner IPv6 header after the socket buffer skb head has been reallocated. This can...

The vulnerability of the alps_disconnect() function in the drivers/input/mouse/alps.c module of the Linux kernel mouse driver allows a hacker to cause a service failure.

The vulnerability of the alpsdisconnect function in the drivers/input/mouse/alps.c module of the Linux kernel operating system is related to the repeated use of previously freed memory. Exploiting this vulnerability could allow a attacker to cause a service failure...

The vulnerability of the iommu_sva_bind_device() function in the drivers/iommu/iommu-sva.c module of the Linux operating system’s IOMMU driver allows a hacker to cause a service failure.

The vulnerability of the iommusvabinddevice function in the drivers/iommu/iommu-sva.c file of the Linux IOMMU driver relates to the reutilization of previously freed memory. Exploiting this vulnerability can allow an attacker to cause a service failure...

The vulnerability of the asdpciRemove() function in the drivers/scsi/aic94xx/aic94xx_init.c driver for Linux SCSI device drivers allows a hacker to cause a service failure.
