SUSE CVE-2024-46681

In the Linux kernel, the following vulnerability has been resolved: pktgen: use cpusreadlock in pgnetinit I have seen the WARNONsmpprocessorid != cpu firing in pktgenthreadworker during tests. We must use cpusreadlock/cpusreadunlock around the foreachonlinecpucpu loop. While we are at it use...

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a failure to properly handle mutually exclusive locks, potentially leading to data contention...

DEBIAN-CVE-2024-45024

In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: fix hugetlb vs. core-mm PT locking We recently made GUP's common page table walking code to also walk hugetlb VMAs without most hugetlb special-casing, preparing for the future of having less hugetlb-specific page tab...

CVE-2024-45024

CVE-2024-45024 relates to a Linux kernel Hugetlb PT locking issue fixed by aligning huge page table locking with core-mm PT walkers. The root cause: during GUP’s shared page-table walking, hugetlb folios spanning multiple PTEs could be locked using PTE table locks (pte_offset_map_lock) while core...

Unspecified vulnerability in Linux kernel (CNVD-2024-39520)

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a deadlock issue in the xen:privcmd component that may result from the use of mutually exclusive locks. No...

kernel: gfs2: Fix potential glock use-after-free on unmount

A vulnerability was found in the Linux kernel within the gfs2 component, where potential use-after-free issues could occur on unmount. When DLM lockspaces are released with remaining locks, callbacks for asynchronous lock contention may access freed objects, causing unexpected behavior...

CVE-2022-48887

CVE-2022-48887 affects the Linux kernel DRM vmwgfx driver. User-resource lookups previously used RCU paths, which were buggy and could crash when command buffers were submitted from two threads. The fix replaces the RCU-based lookups with a regular spin lock to remove races in accesses to shared ...
