kernel: net: fix out-of-bounds access in ops_init

An out-of-bounds memory access flaw was found in the Linux kernel’s networking subsystem in how a local user triggers a complex race condition. This flaw allows a local user to crash or potentially escalate their privileges on the system...

kernel: net: do not leave a dangling sk pointer, when socket creation fails

A vulnerability was found in the Linux kernel's networking component in the sockrelease function, where a dangling pointer can occur when socket creation fails. This happens when a reference to the socket is not cleared, leading to a use-after-free condition...

kernel: net/sched: act_api: fix possible infinite loop in tcf_idr_check_alloc()

A vulnerability was found in the Linux kernel's networking subsystem in the actapi implementation within the tcfidrcheckalloc function, which lead to a possible infinite loop when multiple actions with the same index are added, causing the second request to block indefinitely while holding the...

kernel: net, sunrpc: Remap EPERM in case of connection failure in xs_tcp_setup_socket

A flaw was found in the Linux kernel's bpf programs. Under certain conditions, when the kernel attempts to initiate a network connection using the kernelconnect function, it can return a value that causes the cxtcpsetupsocket function to loop. This issue can lead to continuous data writing to the...

kernel: net: fix out-of-bounds access in ops_init

An out-of-bounds memory access flaw was found in the Linux kernel’s networking subsystem in how a local user triggers a complex race condition. This flaw allows a local user to crash or potentially escalate their privileges on the system...

SUSE CVE-2022-48910

In the Linux kernel, the following vulnerability has been resolved: net: ipv6: ensure we call ipv6mcdown at most once There are two reasons for addrconfnotify to be called with NETDEVDOWN: either the network device is actually going down, or IPv6 was disabled on the interface. If either of them...

kernel: tipc: fix a possible memleak in tipc_buf_append

In the Linux kernel, the following vulnerability has been resolved: tipc: fix a possible memleak in tipcbufappend skblinearize doesn't free the skb when it fails, so move 'buf = NULL' after skblinearize, so that the skb can be freed on the err path...

The vulnerability of the macvlan_handle_frame() function in the drivers/net/macvlan.c file of the Linux kernel’s networking component allows a hacker to cause a service failure.

The vulnerability of the macvlanhandleframe function in the drivers/net/macvlan.c file of the Linux kernel’s networking component is related to a memory leak. Exploiting this vulnerability allows an attacker to cause a service failure...

kernel: net/mlx5e: xsk: Fix crash on regular rq reactivation

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: xsk: Fix crash on regular rq reactivation When the regular rq is reactivated after the XSK socket is closed it could be reading stale cqes which eventually corrupts the rq. This leads to no more traffic being received ...

kernel: net/packet: slab-out-of-bounds access in packet_recvmsg()

An out-of-bounds access issue was found in the Linux kernel networking subsystem in the way raw packet sockets AFPACKET used PACKETCOPYTHRESH and mmap operations. A local attacker with CAPNETRAW capability could use this flaw to trigger a buffer overflow resulting in a system crash or privilege...

kernel: drm/virtio: Check whether transferred 2D BO is shmem

A flaw was found in the Linux kernel networking subsystem. Under certain conditions, a pointer may be dereferenced without proper validation, resulting in a NULL pointer dereference. An unprivileged local user could trigger this flaw by exercising the affected networking functionality, causing a...

Important: kernel-livepatch-6.1.29-50.88

Issue Overview: A flaw was found in the Linux kernel's networking subsystem within the RPL protocol's handling. This issue results from the improper handling of user-supplied data, which can lead to an assertion failure. This flaw allows an unauthenticated, remote attacker to create a denial of...

kernel: data races around sk->sk_prot

A data race problem was found in sk-skprot in the network subsystem in ipv6 in the Linux kernel. This issue occurs while some functions access critical data, leading to a denial of service...

USN-6000-1 linux-bluefield vulnerabilities

It was discovered that the Upper Level Protocol ULP subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execut...

SUSE CVE-2016-8399

An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler...

kernel: net/packet: slab-out-of-bounds access in packet_recvmsg()

An out-of-bounds access issue was found in the Linux kernel networking subsystem in the way raw packet sockets AFPACKET used PACKETCOPYTHRESH and mmap operations. A local attacker with CAPNETRAW capability could use this flaw to trigger a buffer overflow resulting in a system crash or privilege...

kernel: use-after-free in route4_change() in net/sched/cls_route.c

A flaw was found in the "Routing decision" classifier in the Linux kernel's Traffic Control networking subsystem in the way it handled changing of classification filters, leading to a use-after-free condition. This flaw allows unprivileged local users to escalate their privileges on the system. T...

kernel: tcp: excessive resource consumption for TCP connections with low MSS allows remote denial of service

An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP segments. If the Maximum Segment Size MSS of a TCP connection was set to low values, such as 48 bytes, it can leave as little as 8 bytes for the user data, which significantly increas...
