| Descripción: | Summary:
The remote host is missing an update for the 'kernel, kmod-virtualbox, kmod-xtables-addons' package(s) announced via the MGASA-2022-0092 advisory.
Vulnerability Insight:
This kernel update is based on upstream 5.15.25 and fixes at least the
following security issues:
A vulnerability in the Linux kernel since version 5.8 due to uninitialized
variables. It enables anybody to write arbitrary data to arbitrary files,
even if the file is O_RDONLY, immutable or on a MS_RDONLY filesystem.
It can be used to inject code into arbitrary processes (CVE-2022-0847).
An issue was discovered in drivers/usb/gadget/composite.c in the Linux
kernel before 5.16.10. The USB Gadget subsystem lacks certain validation
of interface OS descriptor requests (ones with a large array index and
ones associated with NULL function pointer retrieval). Memory corruption
might occur (CVE-2022-25258).
An issue was discovered in drivers/usb/gadget/function/rndis.c in the
Linux kernel before 5.16.10. The RNDIS USB gadget lacks validation of
the size of the RNDIS_MSG_SET command. Attackers can obtain sensitive
information from kernel memory (CVE-2022-25375).
net/netfilter/nf_dup_netdev.c in the Linux kernel 5.4 through 5.6.10
allows local users to gain privileges because of a heap out-of-bounds
write. This is related to nf_tables_offload (CVE-2022-25636).
For other upstream fixes, 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).
