linux-azure-5.4 vulnerabilities
==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 18.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
– linux-azure-5.4: Linux kernel for Microsoft Azure cloud systems<\/p>\n
Details:<\/p>\n
It was discovered that a race condition existed in the Bluetooth subsystem
in the Linux kernel, leading to a null pointer dereference vulnerability. A
privileged local attacker could use this to possibly cause a denial of
service (system crash). (CVE-2024-24860)<\/p>\n
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
– SuperH RISC architecture;
– MMC subsystem;
– Network drivers;
– SCSI drivers;
– GFS2 file system;
– IPv4 networking;
– IPv6 networking;
– HD-audio driver;
(CVE-2024-26830, CVE-2024-39484, CVE-2024-36901, CVE-2024-26929,
CVE-2024-26921, CVE-2021-46926, CVE-2023-52629, CVE-2023-52760)<\/p>\n
Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
package versions:<\/p>\n
Ubuntu 18.04 LTS
linux-image-5.4.0-1136-azure 5.4.0-1136.143~18.04.1
Available with Ubuntu Pro
linux-image-azure 5.4.0.1136.143~18.04.1
Available with Ubuntu Pro<\/p>\n
After a standard system update you need to reboot your computer to make
all the necessary changes.<\/p>\n
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.<\/p>\n
