CVE-2026-25271 Time-of-check Time-of-use (TOCTOU) Race Condition in DSP Service

Memory Corruption when processing asynchronous input parameters due to improper handling of modified values between check and use...

CVE-2026-45258

dspmmapsingle validated the requested mapping by checking the sum of the user-supplied offset and length against the buffer size. This addition could overflow, so that a large offset and length wrapped around and passed the check. The offset was then narrowed from 64 to 32 bits when converted to ...

CVE-2026-45258

The CVE-2026-45258 issue affects FreeBSD sound(4) mmap support. dsp_mmap_single() overflows when validating the requested mapping because offset+length can wrap the size check, and the offset is reduced from 64 to 32 bits for the buffer address, allowing a mapping that extends past the audio buff...

CVE-2026-49417

CVE-2026-49417 is part of two memory-safety issues in FreeBSD’s sound(4) mmap path. The advisories describe: (1) dsp_mmap_single() could overflow when validating a requested mapping, allowing a mapping to extend past the audio buffer into kernel memory (CVE-2026-45258), and (2) the audio buffer b...

CVE-2026-53161

The CVE-2026-53161 entry concerns a use-after-free in the Linux kernel fastrpc subsystem. A race between fastrpc_device_release() (on file close) and the workqueue processing DSP responses can free the fastrpc_user while an in-flight DSP invocation is completing, leading to dereferencing freed co...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15

A race condition flaw was discovered in the Linux kernel sound subsystem due to improper locking mechanisms. This could lead to a NULL pointer derefrence during the handling of the SNDCTLDSPSYNC ioctl command. A privileged local user such as root or a member of the audio group could exploit this...
