Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, caused by a type error in the parameters of the bpfxdpstorebytes function. This error allows the verifier to...

📄 macOS 18.3.2 Kernel Privilege Escalation

macOS version 18.3.2 proof of concept exploit for an old kernel related privilege escalation vulnerability. A critical memory management vulnerability exists within the macOS XNU kernel's handling of the VMBEHAVIORZEROWIREDPAGES behavior flag. The issue arises from improper sequence validation wh...

SUSE CVE-2022-2590

A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write COW breakage of private read-only shared memory mappings. This flaw allows an unprivileged, local user to gain write access to read-only memory mappings, increasing their privileges on the system...

DEBIAN-CVE-2016-5195

Race condition in mm/gup.c in the Linux kernel 2.x through 4.x before 4.8.3 allows local users to gain privileges by leveraging incorrect handling of a copy-on-write COW feature to write to a read-only memory mapping, as exploited in the wild in October 2016, aka "Dirty COW."...

kernel: mm: privilege escalation via MAP_PRIVATE COW breakage

A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write COW breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on...

kernel: mm: privilege escalation via MAP_PRIVATE COW breakage

A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write COW breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on...

USN-3106-4 linux-snapdragon vulnerability

It was discovered that a race condition existed in the memory manager of the Linux kernel when handling copy-on-write breakage of private read-only memory mappings. A local attacker could use this to gain administrative privileges...
