Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-006600)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-006600 advisory. An issue was discovered in mm/mmap.c in the Linux kernel before 5.7.11. There is a race condition between certain expand functions expanddownwards and expandupwards...

SUSE CVE-2020-29369

An issue was discovered in mm/mmap.c in the Linux kernel before 5.7.11. There is a race condition between certain expand functions expanddownwards and expandupwards and page-table free operations from an munmap call, aka CID-246c320a8cfe...

The vulnerability of the `expand_downwards` function in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the expanddownwards function in Linux kernel relates to the assignment of the null pointer. Exploiting this vulnerability could allow an attacker to cause a service failure...

The vulnerability of the expand_downwards and expand_upwards functions (mm/mmap.c) in Linux operating systems allows a hacker to trigger a service failure.

The vulnerability of the expanddownwards and expandupwards functions in Linux kernel systems is related to errors during multi-threaded tasks race conditions. Exploiting this vulnerability can allow an attacker to cause service failures...

Linux expand_downwards() Competitive Condition Vulnerability

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A contention condition vulnerability exists in Linux expanddownwards. An attacker can exploit this vulnerability to cause a denial of service with the help of a...

Linux expand_downwards() / munmap() Race Condition

Linux =4.20: expanddownwards can race with munmap page table freeing Since 4.20, domunmap downgrades the mmapsem from write-locked to read-locked after detaching the VMAs from the mmstruct, but before dropping references to pages and freeing page tables. This ought to be safe because VMA tree...

Linux kernel pointer dereference vulnerability

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in the expanddownwards of the mm/mmap.c file in versions of Linux kernel prior to 4.20.14. An attacker can exploit this vulnerability t...

UBUNTU-CVE-2019-9213

In the Linux kernel before 4.20.14, expanddownwards in mm/mmap.c lacks a check for the mmap minimum address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task...
