DESCRIPTION

* CVE-2021-47197, CVE-2021-47438: Denial-of-service in Mellanox 5 network adapter driver core.

A logic error when using the Mellanox 5 driver core could lead to a
memory leak. A local attacker could use this flaw to cause a denial-of-
service.

Orabug: 37104452, 37099360


* CVE-2024-41012, CVE-2024-41020: Information leak in core filesystem layer.

A race condition when using the core filesystem layer could lead to a
use-after-free. A local attacker could use this flaw to extract
sensitive information.


* CVE-2024-41015: Disk corruption in OCFS2 filesystem.

A missing check when using the OCFS2 filesystem could lead to an out-of-
bounds memory access. A local attacker could use this flaw to cause disk
corruption.


* CVE-2024-41072: Privilege escalation in core WiFi subsystem.

A missing check when using the core WiFi subsystem could lead to an out-
of-bounds memory access. A local attacker could use this flaw to cause a
denial-of-service or potentially escalate privileges.


* Denial-of-service in InfiniBand driver during multi-connection setup.

A logic error when using the InfiniBand driver could lead to hogging the
rtnl_lock when setting up many RDMA connections. A local attacker could
use this flaw to cause a denial-of-service.
