Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of kernel installed on the remote host is prior to 5.4.224-128.414. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-039 advisory.

A memory overflow vulnerability was found in the Linux kernel's ipc functionality of the memcg subsystem, in the way a user calls the semget function multiple times, creating semaphores. This flaw allows a local user to starve the resources, causing a denial of service. The highest threat from this vulnerability is to system availability. (CVE-2021-3759)

In the Linux kernel, the following vulnerability has been resolved:

inet: fully convert sk->sk_rx_dst to RCU rules (CVE-2021-47103)

A use-after-free flaw was found in the Linux kernel's Unix socket Garbage Collection and io_uring. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2602)

A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this vulnerability is the function ipv6_renew_options of the component IPv6 Handler. The manipulation leads to memory leak. The attack can be launched remotely. It is recommended to apply a patch to fix this issue.
The identifier VDB-211021 was assigned to this vulnerability. (CVE-2022-3524)

A vulnerability classified as problematic was found in Linux Kernel. Affected by this vulnerability is the function mvpp2_dbgfs_port_init of the file drivers/net/ethernet/marvell/mvpp2/mvpp2_debugfs.c of the component mvpp2. The manipulation leads to memory leak. It is recommended to apply a patch to fix this issue. The identifier VDB-211033 was assigned to this vulnerability. (CVE-2022-3535)

A vulnerability classified as problematic was found in Linux Kernel. This vulnerability affects the function bnx2x_tpa_stop of the file drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c of the component BPF.
The manipulation leads to memory leak. It is recommended to apply a patch to fix this issue. VDB-211042 is the identifier assigned to this vulnerability. (CVE-2022-3542)

A vulnerability classified as critical was found in Linux Kernel. Affected by this vulnerability is the function l2cap_reassemble_sdu of the file net/bluetooth/l2cap_core.c of the component Bluetooth. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211087. (CVE-2022-3564)

A vulnerability, which was classified as critical, has been found in Linux Kernel. Affected by this issue is the function del_timer of the file drivers/isdn/mISDN/l1oip_core.c of the component Bluetooth. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-211088. (CVE-2022-3565)

A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this vulnerability is the function intr_callback of the file drivers/net/usb/r8152.c of the component BPF. The manipulation leads to logging of excessive data. The attack can be launched remotely. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211363.
(CVE-2022-3594)

A vulnerability was found in Linux Kernel. It has been classified as problematic. Affected is the function nilfs_new_inode of the file fs/nilfs2/inode.c of the component BPF. The manipulation leads to use after free. It is possible to launch the attack remotely. It is recommended to apply a patch to fix this issue.
The identifier of this vulnerability is VDB-211992. (CVE-2022-3649)

drivers/video/fbdev/smscufx.c in the Linux kernel through 5.19.12 has a race condition and resultant use- after-free if a physically proximate attacker removes a USB device while calling open(), aka a race condition between ufx_ops_open and ufx_usb_disconnect. (CVE-2022-41849)

roccat_report_event in drivers/hid/hid-roccat.c in the Linux kernel through 5.19.12 has a race condition and resultant use-after-free in certain situations where a report is received while copying a report->value is in progress. (CVE-2022-41850)
