CVE-2026-90397

CVE-2026-90397 affects the Qualcomm SCM (Secure Channel Manager) driver in the Linux kernel . The root cause is a race condition in qcom_scm_probe(): devm_request_threaded_irq() is called before __scm is published via smp_store_release(), allowing two code paths (the IRQ handler and non-atomic SM...

CVE-2026-90385

This Linux kernel vulnerability affects the md/raid1 module. When a new rdev is added to an existing RAID1 array with serialize_policy enabled, the condition in mddev_create_serial_pool() skips initialization of rdev->serial. The wait_for_serialization() function then dereferences an uninitial...

CVE-2026-90378 wifi: mt76: mt792x: Fix memory leak in SDIO TX path

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt792x: Fix memory leak in SDIO TX path When txprepareskb returns an error in the SDIO TX path, the skb is not freed, leading to a memory leak. This can occur when zero-length frames such as WNM NULL frames are droppe...

CVE-2026-90374 wifi: mt76: mt7996: validate RX band_idx before dereferencing phys[]

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: validate RX bandidx before dereferencing phys bandidx comes from a 2-bit descriptor field 0-3 and was used directly to index dev-mt76.phys size MTMAXBAND == 3 and dereference the result.

CVE-2026-90337

CVE-2026-90337 is a Linux kernel vulnerability in the serial core . In serial_core_add_one_port(), the uport->tty_groups and uport->name allocations occur after uart_configure_port() registers the console. If an allocation fails, the driver unwinds the port while its console remains registe...

EUVD-2026-81996

In the Linux kernel, the following vulnerability has been resolved: tty: skip cdevdel when no cdev is registered TTY device registration can fail before a cdev is allocated. Serial core keeps the port so setserial can still use it, and later removal passes the NULL cdev slot to cdevdel, causing a...

CVE-2026-90335

CVE-2026-90335 is a NULL-pointer dereference in the Linux kernel's TTY subsystem (serial core). When TTY device registration fails before a cdev is allocated, the serial core retains the port for use by setserial. On later removal, the NULL cdev slot is passed to cdev_del(), triggering the derefe...
