important: kernel security update
important
An update for kernel is now available for NewStart CGSL MAIN 6.02.
NewStart Security has rated this update as having a security impact of important. A Common Vunlnerability Scoring System(CVSS)base score, which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
kernel: The python3-perf package contains a module that permits applications written in the Python programming language to use the interface to manipulate perf events.
Security Fix(es):
kernel: A use-after-free flaw was found in slcan_write_wakeup in drivers/net/can/slcan.c in the serial CAN module slcan. A race condition occurs when communicating with can using slcan between the write (scheduling the transmit) and closing (flushing out any pending queues) the SLCAN channel. This flaw allows a local attacker with special user or root privileges to cause a denial of service or a kernel information leak. The highest threat from this vulnerability is to system availability.(CVE-2020-14416)
kernel: A random memory access flaw was found in the Linux kernel?s GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or escalate their privileges on the system.(CVE-2022-0330)
kernel: A stack overflow flaw was found in the Linux kernel?s TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed. This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network.(CVE-2022-0435)
kernel: An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system.(CVE-2022-2639)
kernel: A memory leak flaw was found in bnx2x_tpa_stop in drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c in the bnx2x sub-component in the Linux Kernel. This flaw may allow a local attacker to cause a denial of service.(CVE-2022-3542)
kernel: A vulnerability has been found in Linux Kernel and classified as critical. Affected by this vulnerability is the function area_cache_get of the file drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c of the component IPsec. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The identifier VDB-211045 was assigned to this vulnerability.(CVE-2022-3545)
kernel: A flaw was found in the Linux kernel’s networking code. A use-after-free was found in the way the sch_sfb enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and freed) into a child qdisc. This flaw allows a local, unprivileged user to to disclose sensitive information or crash the system, causing a denial of service.(CVE-2022-3586)
kernel: A vulnerability was found in intr_callback in drivers/net/usb/r8152.c in the BPF component in the Linux Kernel. The manipulation leads to logging excessive data, where an attack can be launched remotely.(CVE-2022-3594)
kernel: An information disclosure vulnerability is found in stex_queuecommand_lck() in drivers/scsi/stex.c in the Linux Kernel. This flaw allows a local attacker to disclose sensitive information such as kernel space address.(CVE-2022-40768)
kernel: A use-after-free flaw was found in the Linux kernel’s dvb-core subsystem (DVB API used by Digital TV devices) in how a user physically removed a USB device (such as a DVB demultiplexer device) while running malicious code. This flaw allows a local user to crash or potentially escalate their privileges on the system.(CVE-2022-41218)
kernel: An out-of-bounds memory write flaw in the Linux kernel’s USB Monitor component was found in how a user with access to the /dev/usbmon can trigger it by an incorrect write to the memory of the usbmon. This flaw allows a local user to crash or potentially escalate their privileges on the system.(CVE-2022-43750)
