EUVD-2026-48800

In the Linux kernel, the following vulnerability has been resolved: hwrng: virtio: clamp device-reported used.len at copydata randomrecvdone stores the device-reported used.len directly into vi-dataavail. copydata then indexes vi-data using vi-dataidx advanced by previous copydata calls and issue...

CVE-2026-64311 crypto: loongson - Remove broken and unused loongson-rng

In the Linux kernel, the following vulnerability has been resolved: crypto: loongson - Remove broken and unused loongson-rng The loongson-rng rngalg has several vulnerabilities, including not providing forward security, and a use-after-free bug due to the use of waitforcompletioninterruptible...

The vulnerability of the geode_rng_init() function in the drivers/char/hw_random/geode-rng.c module of the Linux operating system’s character device driver framework allows a attacker to cause a service failure.

The vulnerability of the geodernginit function in the drivers/char/hwrandom/geode-rng.c file of the Linux kernel’s alphabetic devices driver is related to errors during the update of the reference counter. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2026-3290

Timing limitations of the HRNG in RS9116 when power save mode is enabled results in predictable values...

CVE-2026-45949

A flaw was found in the Linux kernel's hardware random number generator hwrng core. A race condition exists where concurrent or rapid calls to the hwrngunregister function can lead to a use-after-free vulnerability. This issue allows the system to attempt to access freed memory, potentially causi...

EUVD-2026-32233

In the Linux kernel, the following vulnerability has been resolved: hwrng: core - use RCU and workstruct to fix race condition Currently, hwrngfill is not cleared until the hwrngfillfn thread exits. Since hwrngunregister reads hwrngfill outside the rngmutex lock, a concurrent hwrngunregister may...

UBUNTU-CVE-2026-46075

In the Linux kernel, the following vulnerability has been resolved: crypto: atmel-sha204a - Fix potential UAF and memory leak in remove path Unregister the hwrng to prevent new -read calls and flush the Atmel I2C workqueue before teardown to prevent a potential UAF if a queued callback runs while...

CVE-2026-45949 hwrng: core - use RCU and work_struct to fix race condition

In the Linux kernel, the following vulnerability has been resolved: hwrng: core - use RCU and workstruct to fix race condition Currently, hwrngfill is not cleared until the hwrngfillfn thread exits. Since hwrngunregister reads hwrngfill outside the rngmutex lock, a concurrent hwrngunregister may...

CVE-2026-45949

CVE-2026-45949 details from connected OSV/NVD entries confirm a race in the Linux kernel hwrng core where concurrent unregister/start calls may cause use-after-free due to hwrng_fill not being cleared reliably. The patch serializes access with rng_mutex, moves cleanup to a work_struct, and conver...

PT-2026-43816

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A race condition exists in the hardware random number generator hwrng core. The hwrng fill pointer is not cleared until the hwrng fillfn thread exits. Because hwrng unregister reads hwrn...

CVE-2026-3290

CVE-2026-3290 affects the HRNG in the RS9116. When power-save mode is enabled, timing limitations produce predictable random values, as described in the connected records. The CVSS 4.0 vector indicates high impact on confidentiality and integrity with adjacent access and no privileges, and passiv...
