CVE-2026-74640

This is an out-of-bounds write in the Linux kernel's ALSA FCP (FireWire Control Protocol) driver, specifically in fcp_meter_ctl_get(). The root cause is a mismatch: fcp_ioctl_set_meter_map() permits a Level Meter map size up to 255 , but the destination buffer struct snd_ctl_elem_value declares l...

CVE-2026-74640 ALSA: FCP: fix OOB write in fcp_meter_ctl_get()

In the Linux kernel, the following vulnerability has been resolved: ALSA: FCP: fix OOB write in fcpmeterctlget fcpioctlsetmetermap bounds the user-supplied Level Meter map size by the driver's own limit of 255 if map.mapsize 255 || map.meterslots 255 return -EINVAL; and passes it to fcpaddnewctl ...

CVE-2026-74638

CVE-2026-74638 affects the V3D DRM scheduler in the Linux kernel, used on hardware such as the Raspberry Pi 5 . The V3D GPU exposes multiple independent hardware queues (BIN, RENDER, TFU, CSD) but performs only a single global reset . When a timeout on one queue triggers a global reset while anot...

CVE-2026-74636

CVE-2026-74636 is a race condition in the Linux kernel tracing subsystem. When two modules are loaded concurrently on different CPUs, event_define_fields() and update_event_fields() can access class->fields simultaneously without proper mutual exclusion. Specifically, trace_event_update_all() ...

CVE-2026-74637

CVE-2026-74637 is a use-after-free in the Linux kernel's perf subsystem . When a perf event group sibling is detached during CPU hotplug (DETACH_GROUP), it is removed from the leader's sibling list but its group_leader pointer is left stale. If the leader is later freed, a PERF_IOC_FLAG_GROUP ioc...
