Título:	Mageia: Security Advisory (MGASA-2023-0166)
Resumen:	The remote host is missing an update for the 'kernel, kmod-virtualbox, kmod-xtables-addons' package(s) announced via the MGASA-2023-0166 advisory.
Descripción:	Summary: The remote host is missing an update for the 'kernel, kmod-virtualbox, kmod-xtables-addons' package(s) announced via the MGASA-2023-0166 advisory. Vulnerability Insight: This kernel update is based on upstream 5.15.110 and fixes at least the following security issues: A slab-out-of-bound read problem was found in brcmf_get_assoc_ies in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c. This issue could occur when assoc_info->req_len data is bigger than the size of the buffer, defined as WL_EXTRA_BUF_MAX, leading to a denial of service (CVE-2023-1380). It was discovered that a race condition existed in the Xen transport layer implementation for the 9P file system protocol in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or expose sensitive information (CVE-2023-1859). An insufficient permission check has been found in the Bluetooth subsystem of the Linux kernel when handling ioctl system calls of HCI sockets. This causes tasks without the proper CAP_NET_ADMIN capability can easily mark HCI sockets as _trusted_. Trusted sockets are intended to enable the sending and receiving of management commands and events, such as pairing or connecting with a new device. As a result, unprivileged users can acquire a trusted socket, leading to unauthorized execution of management commands (CVE-2023-2002). A heap out-of-bounds read/write vulnerability in the Linux Kernel traffic control (QoS) subsystem can be exploited to achieve local privilege escalation. The qfq_change_class function does not properly limit the lmax variable which can lead to out-of-bounds read/write. If the TCA_QFQ_LMAX value is not offered through nlattr, lmax is determined by the MTU value of the network device. The MTU of the loopback device can be set up to 2^31-1 and as a result, it is possible to have an lmax value that exceeds QFQ_MIN_LMAX (CVE-2023-2248). qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write because lmax can exceed QFQ_MIN_LMAX (CVE-2023-31436). Linux kernel use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary reads and writes in kernel memory. An unprivilegied local user can exploit this to start a local root shell (CVE-2023-32233). For other upstream fixes in this update, see the referenced changelogs. Affected Software/OS: 'kernel, kmod-virtualbox, kmod-xtables-addons' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:L/AC:L/Au:S/C:C/I:C/A:C
