Linux kernel 安全漏洞

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 memory leak warning caused by a percpu pointer not being 8-byte aligned...

PT-2025-20336

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A memory leak issue has been identified in the Linux kernel, specifically in the bpf Berkeley Packet Filter module. The issue arises due to the non-8-byte aligned storage of percpu...

SUSE CVE-2023-53044

In the Linux kernel, the following vulnerability has been resolved: dm stats: check for and propagate allocpercpu failure Check allocprecpu's return value and return an error from dmstatsinit if it fails. Update allocdev to fail if dmstatsinit does. Otherwise, a NULL pointer dereference will occu...

CVE-2023-53044

The CVE-2023-53044 entry concerns a Linux kernel vulnerability in the dm-stats path. A NULL pointer dereference can occur in dm_stats_cleanup() if alloc_percpu() fails during dm_stats_init(), with the failure not being properly propagated from alloc_precpu() or dm_stats_init() to dm_stats_cleanup...
