OESA-2024-2192 python3 security update

Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems. New built-in modules are easily written in C or C...

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 Linux kernel that stems from a leak in the handling of sk reference counts...

QEMU: Denial of Service via Improper Synchronization in QEMU NBD Server During Socket Closure

A flaw was found in the QEMU NBD Server. This vulnerability allows a denial of service DoS attack via improper synchronization during socket closure when a client keeps a socket open as the server is taken offline...

kernel: net/sched: act_mirred: don't override retval if we already lost the skb

A use-after-free flaw was found in net/sched/actmirred.c in the Linux kernel. This may result in a crash...

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: udp: Set SOCK_RCU_FREE earlier in udp_lib_get_port()

In the Linux kernel, the following vulnerability has been resolved: udp: Set SOCKRCUFREE earlier in udplibgetport. syzkaller triggered the warning 0 in udpv4earlydemux. In udpv46earlydemux and sklookup, we do not touch the refcount of the looked-up sk and use sockpfree as skb-destructor, so we...

kernel: af_unix: Fix garbage collector racing against connect()

A flaw was found in the Linux kernel, where the management of inter-process communication uses AFUNIX sockets. The issue arises from a race condition where a partially initialized socket with specific permissions carrying SCMRIGHTS is improperly handled during garbage collection. This situation...

kernel: vsock: remove vsock from connected table when connect is interrupted by a signal

A vulnerability was found in the Linux kernel's vsock subsystem's vsockstreamconnect function where improper handling of the socket state can lead to the connected table's list being corrupted. This occurs when a signal interrupt occurs and resets the socket's state without removing it from the...

kernel: SUNRPC: lock against ->sock changing during sysfs read

A vulnerability was found in the Linux kernel's SUNRPC component, where a race condition exists during sysfs read operations due to improper handling of the -sock pointer. If the mutex -recvmutex is not held, -sock may change asynchronously, leading to a potential kernel oops. This vulnerability...

SUSE CVE-2024-46717

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: SHAMPO, Fix incorrect page release Under the following conditions: 1 No skb created yet 2 headersize == 0 no SHAMPO header 3 headerindex + 1 % MLX5ESHAMPOWQHEADERPERPAGE == 0 this is the last page fragment of a SHAMPO...

SUSE CVE-2024-46763

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...
