CVE-2022-49989

In the Linux kernel, the following vulnerability has been resolved: xen/privcmd: fix error exit of privcmdioctldmop The error exit of privcmdioctldmop is calling unlockpages potentially with pages being NULL, leading to a NULL dereference. Additionally lockpages doesn't check for pinuserpagesfast...

CVE-2022-49989

CVE-2022-49989 concerns the Linux kernel’s xen/privcmd code. The vulnerability stems from: (1) error exit handling in privcmd_ioctl_dm_op() calling unlock_pages() with NULL pages, risking a NULL dereference, and (2) lock_pages() not verifying pin_user_pages_fast() success, potentially leaving som...

Integer Overflows

The kernel packages contain the Linux kernel, the core of any Linux operating system. A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol SCTP implementation handled simultaneous connections between the same hosts. A remote attacker could u...

Kernel: mm: try_to_unmap_cluster() should lock_page() before mlocking

It was found that the trytounmapcluster function in the Linux kernel's Memory Managment subsystem did not properly handle page locking in certain cases, which could potentially trigger the BUGON macro in the mlockvmapage function. A local, unprivileged user could use this flaw to crash the system...
