DESCRIPTION

* CVE-2024-39468: Denial-of-service in SMB3 and CIFS driver.

A locking error when using the SMB3 and CIFS driver could lead
to a deadlock. An attacker could use this flaw to cause a
denial-of-service.


* CVE-2024-42283: Remote information leak in TCP/IP networking stack.

A missing variable initialization when using the TCP/IP networking stack
could lead to exposure of kernel memory to userspace. A remote attacker
could use this flaw to extract sensitive information.


* CVE-2024-46824: Denial-of-service in IOMMU subsystem.

A missing check when using the IOMMU subsystem IOMMU_HWPT_INVALIDATE
ioctl could lead to a NULL pointer dereference. A local attacker could
use this flaw to cause a denial-of-service.


* CVE-2024-46858: Privilege escalation in Multipath TCP driver.

A logic error when using the Multipath TCP driver could lead to a
use-after-free. A local attacker could use this flaw to escalate
privileges.


* CVE-2024-49880: Denial-of-service in The Extended 4 (ext4) filesystem driver.

A logic error when resizing the The Extended 4 (ext4) filesystem
