| Description: | Summary:
The remote host is missing an update for the 'kernel, kmod-virtualbox, kmod-xtables-addons, xtables-addons' package(s) announced via the MGASA-2022-0154 advisory.
Vulnerability Insight:
This kernel update is based on upstream 5.15.35 and fixes at least the
following security issues:
A denial of service (DOS) issue was found in the Linux kernel
smb2_ioctl_query_info function in the fs/cifs/smb2ops.c Common Internet
File System (CIFS) due to an incorrect return from the memdup_user function.
This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the
system (CVE-2022-0168).
x86/kvm: cmpxchg_gpte can write to pfns outside the userspace region
(CVE-2022-1158).
Use-after-free vulnerabilities in drivers/net/hamradio/6pack.c allow
attacker to crash linux kernel by simulating Amateur Radio from user-space
(CVE-2022-1198).
Use-after-free flaw was found in the Linux kernel's Amateur Radio AX.25
protocol functionality in the way a user connects with the protocol. This
flaw allows a local user to crash the system (CVE-2022-1204).
A NULL pointer dereference flaw was found in the Linux kernel's Amateur
Radio AX.25 protocol functionality in the way a user connects with the
protocol. This flaw allows a local user to crash the system
(CVE-2022-1205).
A null pointer dereference was found in the kvm module which can lead to
denial of service (CVE-2022-1263).
A vulnerability was found in the pfkey_register function in net/key/af_key.c
in the Linux kernel. This flaw allows a local, unprivileged user to gain
access to kernel memory, leading to a system crash or a leak of internal
kernel information (CVE-2022-1353).
usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel
through 5.17.1 has a double free (CVE-2022-28388).
mcba_usb_start_xmit in drivers/net/can/usb/mcba_usb.c in the Linux kernel
through 5.17.1 has a double free (CVE-2022-28389).
ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel
through 5.17.1 has a double free (CVE-2022-28390).
In the Linux kernel before 5.17.3, fs/io_uring.c has a use-after-free due
to a race condition in io_uring timeouts. This can be triggered by a local
user who has no access to any user namespace (CVE-2022-29582).
Other fixes in this update:
- gpio: Request interrupts after IRQ is initialized
- net: atlantic: invert deep par in pm functions, preventing null derefs
- xtables-addons have been updated to 3.20
For other upstream fixes, see the referenced changelogs.
Affected Software/OS:
'kernel, kmod-virtualbox, kmod-xtables-addons, xtables-addons' package(s) on Mageia 8.
Solution:
Please install the updated package(s).
