Linux kernel security vulnerabilities

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 the possibility that MHI ulcallback may be called immediately after a skb has queued for transmission, causi...

OESA-2024-1178 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: Transmit requests in Xen's virtual network protocol can consist of multiple parts. While not really useful, except for the initial part any of them may be of zero length, i.e. carry no data at all. Besides a certain initial porti...

kernel: use after free in unix_stream_sendpage

A use-after-free flaw was found in the Linux kernel's afunix component that allows local privilege escalation. The unixstreamsendpage function tries to add data to the last skb in the peer's recv queue without locking the queue. This issue leads to a race condition where the unixstreamsendpage...

OESA-2024-1083 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: A flaw was found in the Bluetooth subsystem of the Linux kernel. A race condition between the btsockrecvmsg and btsockioctl functions could lead to a use-after-free on a socket buffer "skb". This flaw allows a local user to cause...

A use-after-free flaw was found in the Linux Kernel due to a race problem in the unix garbage collector's deletion of SKB races with unixstreamreadgeneric on the socket that the SKB is queued on...

USN-6536-1: Linux kernel vulnerabilities

Lucas Leong discovered that the netfilter subsystem in the Linux kernel did not properly validate some attributes passed from userspace. A local attacker could use this to cause a denial of service system crash or possibly expose sensitive information kernel memory. CVE-2023-39189 Kyle Zeng...

kernel: wifi: ath11k: fix monitor mode bringup crash

A null pointer dereference vulnerability was found in the ath11k wireless driver in the Linux kernel. When an interface is brought up in monitor mode, the driver attempts to extract packet type from RAW monitor ring packets, which lack the expected structure. This causes a kernel crash due to...

kernel: Linux kernel: Local denial of service in skbuff due to improper network buffer handling

A flaw was found in the Linux kernel. A local user with low privileges could trigger a kernel bug by manipulating network packet buffer skbuff operations. Specifically, when a program uses a helper function to read data beyond the allocated buffer in certain Generic Segmentation Offload GSO...

kernel: Linux kernel: Memory leak in wilc1000 Wi-Fi driver causes Denial of Service

A flaw was found in the Linux kernel's wilc1000 Wi-Fi driver. A local attacker with low privileges could exploit a memory leak in the wilcmacxmit function, which fails to free a socket buffer skb under certain conditions. This resource exhaustion vulnerability can lead to a Denial of Service DoS ...
