CVE-2022-49590

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2022-49590
In the Linux kernel, the following vulnerability has been resolved: igmp: Fix data-races around sysctl_igmp_llm_reports. While reading sysctl_igmp_llm_reports, it can be changed concurrently. Thus, we need to add READ_ONCE() to its readers. This test can be packed into a helper, so such changes will be in the follow-up series after net is merged into net-next. if (ipv4_is_local_multicast(pmc->multiaddr) && !READ_ONCE(net->ipv4.sysctl_igmp_llm_reports))

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: igmp: Se corrigen las ejecuciones de datos en torno a sysctl_igmp_llm_reports. Al leer sysctl_igmp_llm_reports, se puede cambiar simultáneamente. Por lo tanto, debemos agregar READ_ONCE() a sus lectores. Esta prueba se puede empaquetar en un asistente, por lo que dichos cambios estarán en la serie de seguimiento después de que net se fusione con net-next. if (ipv4_is_local_multicast(pmc->multiaddr) && !READ_ONCE(net->ipv4.sysctl_igmp_llm_reports))
