PT-2026-53063

Name of the Vulnerable Software and Affected Versions The product name cannot be determined affected versions not specified Description An issue exists where the audio buffer backing a mapping could be freed upon closing the device while the mapping remains valid. This allows the freed memory to ...

CVE-2026-45258: Out-of-bounds Read

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-2026-49417: Use After Free

Second, the audio buffer backing a mapping could be freed when the device was closed even though the mapping remained valid. The freed memory could then be reused elsewhere while still accessible through the stale mapping. The /dev/dsp device nodes are world-accessible by default. On a system wit...
