UBUNTU-CVE-2026-74715

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix netns reference imbalance in conntrack kfuncs The opts argument of the BPF conntrack kfuncs can point to a shared map value. bpfnfctlookup and bpfnfctallocentry read opts-netnsid separately when acquiring and releasing t...

UBUNTU-CVE-2026-74717

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: fwtracer, return NULL on create error Tracer creation can fail by returning either NULL or ERRPTR. The return value is stored without a check on the device, and users treat ERRPTR and NULL the same way. This also causes...

CVE-2026-74728

CVE-2026-74728 is a NULL pointer dereference in the Linux kernel's XFS filesystem repair tooling. When xfs_buf_alloc_backing_mem() fails, xfs_buf_free() is called with bp->b_addr still NULL. The code then falls through to the folio_put path, which calls virt_to_folio(NULL), dereferencing an in...

CVE-2026-74717

A denial-of-service vulnerability in the Linux kernel's net/mlx5 firmware tracer (fw_tracer). The tracer creation function can return either NULL or ERR_PTR on failure, but the core dump logic (mlx5_fw_tracer_trigger_core_dump_general) does not check for ERR_PTR and dereferences it, leading to a ...

CVE-2026-74702

CVE-2026-74702 affects the vhost-scsi component of the Linux kernel. The root cause is that vhost_scsi_setup_vq_cmds() allocates the protection scatterlist array (prot_sgl) based on the VIRTIO_SCSI_F_T10_PI feature bit at endpoint setup, but command pools are not rebuilt when VHOST_SET_FEATURES l...

In the Linux kernel, the following vulnerability has been resolved: vhost-scsi: reject feature changes after endpoint vhostscsisetupvqcmds runs from VHOSTSCSISETENDPOINT and allocates each command's protection scatterlist array protsgl according to the acknowledged VIRTIOSCSIFT10PI bit. The comma...

EUVD-2026-64390

In the Linux kernel, the following vulnerability has been resolved: vhost-scsi: Validate T10 PI scatterlist counts When T10 PI is negotiated, vhost-scsi splits protection bytes from the data iterator before mapping the request scatterlists. A malformed request can claim protection bytes that cove...

In the Linux kernel, the following vulnerability has been resolved: mm/damon/lrusort: error out for 10000 activemembp damosquotascore can trigger division by zero if the target value is zero. DAMONLRUSORT lets users set the target value for the hot memory scheme via activemembp parameter. It avoi...

CVE-2026-74633

CVE-2026-74633 is a NULL pointer dereference in the Linux kernel's ftrace tracing subsystem. When a module-only event filter (e.g., :mod:foo) is cached while the module is not yet loaded, event_mod->match remains NULL. A subsequent write attempting to remove a specific match from that module p...
