AZL-49584 CVE-2024-46763 affecting package kernel for versions less than 5.15.167.1-1

In the Linux kernel, the following vulnerability has been resolved: fou: Fix null-ptr-deref in GRO. We observed a null-ptr-deref in fougroreceive while shutting down a host. 0 The NULL pointer is sk-skuserdata, and the offset 8 is of protocol in struct fou. When fourelease is called due to netns...

DEBIAN-CVE-2024-44991

In the Linux kernel, the following vulnerability has been resolved: tcp: prevent concurrent execution of tcpskexitbatch Its possible that two threads call tcpskexitbatch concurrently, once from the cleanupnet workqueue, once from a task that failed to clone a new netns. In the latter case, error...

UBUNTU-CVE-2022-48935

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: unregister flowtable hooks on netns exit Unregister flowtable hooks before they are releases via nftablesflowtabledestroy otherwise hook core reports UAF. BUG: KASAN: use-after-free in...

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 failure to properly deregister the flowtable hook on netns exit, resulting in a memory reuse after release...

SUSE CVE-2024-42270

In the Linux kernel, the following vulnerability has been resolved: netfilter: iptables: Fix null-ptr-deref in iptablenattableinit. We had a report that iptables-restore sometimes triggered null-ptr-deref at boot time. 0 The problem is that iptablenattableinit is exposed to user space before the...

kernel: netns: Make get_net_ns() handle zero refcount net

A vulnerability was found in the Linux kernel's netns in the getnetns function. This vulnerability occurs when a network namespace reference count is zero, leading to a use-after-free condition that can trigger a kernel panic...

kernel: tcp: properly terminate timers for kernel sockets

In the Linux kernel, the following vulnerability has been resolved: tcp: properly terminate timers for kernel sockets We had various syzbot reports about tcp timers firing after the corresponding netns has been dismantled. Fortunately Josef Bacik could trigger the issue more often, and could test...

SUSE CVE-2024-42078

In the Linux kernel, the following vulnerability has been resolved: nfsd: initialise nfsdinfo.mutex early. nfsdinfo.mutex can be dereferenced by svcpoolstatsstart immediately after the new netns is created. Currently this can trigger an oops. Move the initialisation earlier before it can possibly...

kernel: ipv6: fix potential "struct net" leak in inet6_rtm_getaddr()

A flaw was discovered in the Linux kernel's IPv6 implementation, specifically within the inet6rtmgetaddr function. The issue arises when user space provides a valid IFATARGETNETNSID value but omits the IFAADDRESS and IFALOCAL attributes. In such cases, the function returns an -EINVAL error while...

CVE-2024-41010

CVE-2024-41010 concerns a Linux kernel vulnerability in the BPF tcx_entry management for old-style ingress/clsact qdiscs. The issue is a use-after-free caused by releasing tcx_entry too early when a shared tc block is replaced, enabling a local attacker to trigger a UAF through a specific qdisc s...
