UBUNTU-CVE-2024-0564

A flaw was found in the Linux kernel's memory deduplication mechanism. The max page sharing of Kernel Samepage Merging KSM, added in Linux kernel version 4.4.0-96.119, can create a side channel. When the attacker and the victim share the same host and the default setting of KSM is "max page...

kernel: race condition in xfrm_probe_algs can lead to OOB read/write

A race condition was found in the Linux kernel's IP framework for transforming packets XFRM subsystem when multiple calls to xfrmprobealgs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an...

Linux kernel code issue vulnerability (CNVD-2024-06235)

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A code issue vulnerability exists in the Linux kernel that stems from vhostnewmsg in drivers/vhost/vhost.c failing to properly initialize memory in messages passed between a...

CVE-2024-0443 Kernel: blkio memory leakage due to blkcg and some blkgs are not freed after they are made offline.

A flaw was found in the blkgs destruction path in block/blk-cgroup.c in the Linux kernel, leading to a cgroup blkio memory leakage problem. When a cgroup is being destroyed, cgrouprstatflush is only called at cssreleaseworkfn, which is called when the blkcg reference count reaches 0. This circula...
