Linux Kernel Security Vulnerabilities

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the premature release of the CPPI descriptor in the RX path within the icssg-prueth driver. This...

In the Linux kernel, the following vulnerability has been resolved: net/smc: fix NULL dereference and UAF in smctcpsynrecvsock Syzkaller reported a panic in smctcpsynrecvsock 1. smctcpsynrecvsock is called in the TCP receive path softirq via icskafops-synrecvsock on the clcsock TCP listening...

kernel: Linux kernel: RDMA/rxe use-after-free vulnerability leading to potential arbitrary code execution

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem, specifically within the rxe component. This use-after-free vulnerability occurs in the rxecreatecq function. When the rxecqfrominit function fails, the subsequent call to rxecleanup attempts to free memory resource...

Linux kernel Bluetooth L2CAP Buffer Overflow DoS

The vulnerability of the l2caprxstaterecv and l2caprx functions in the net/bluetooth/l2capcore.c module of the Linux kernel’s Bluetooth subsystem is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality,...
