CVE-2025-38078 (GCVE-0-2025-38078)

Vulnerability from cvelistv5 – Published: 2025-06-18 09:33 – Updated: 2025-11-03 17:33
VLAI?
Summary
In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Fix race of buffer access at PCM OSS layer The PCM OSS layer tries to clear the buffer with the silence data at initialization (or reconfiguration) of a stream with the explicit call of snd_pcm_format_set_silence() with runtime->dma_area. But this may lead to a UAF because the accessed runtime->dma_area might be freed concurrently, as it's performed outside the PCM ops. For avoiding it, move the code into the PCM core and perform it inside the buffer access lock, so that it won't be changed during the operation.
Severity ?
No CVSS data available.

La capa PCM OSS intenta borrar el b\u00fafer con los datos de silencio durante la inicializaci\u00f3n (o reconfiguraci\u00f3n) de un flujo mediante la llamada expl\u00edcita a snd_pcm_format_set_silence() con runtime-\u0026gt;dma_area. Sin embargo, esto puede generar una UAF, ya que el acceso a runtime-\u0026gt;dma_area podr\u00eda liberarse simult\u00e1neamente, ya que se realiza fuera de las operaciones PCM. Para evitarlo, mueva el c\u00f3digo al n\u00facleo PCM y ejec\u00fatelo dentro del bloqueo de acceso al b\u00fafer, de modo que no se modifique durante la operaci\u00f3n. \"}],\"metrics\":{},\"references\":[{\"url\":\"https://git.kernel.org/stable/c/10217da9644ae75cea7330f902c35fc5ba78bbbf\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/74d90875f3d43f3eff0e9861c4701418795d3455\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/8170d8ec4efd0be352c14cb61f374e30fb0c2a25\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/93a81ca0657758b607c3f4ba889ae806be9beb73\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/afa56c960fcb4db37f2e3399f28e9402e4e1f470\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/bf85e49aaf3a3c5775ea87369ea5f159c2148db4\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/c0e05a76fc727929524ef24a19c302e6dd40233f\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/f3e14d706ec18faf19f5a6e75060e140fea05d4a\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://lists.debian.org/debian-lts-announce/2025/10/msg00007.html\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://lists.debian.org/debian-lts-announce/2025/10/msg00008.html\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"}]}}"
