[USN-5815-1] Linux kernel (BlueField) vulnerabilities

Severity High

Affected Packages 12

CVEs 11

Several security issues were fixed in the Linux kernel.

It was discovered that a race condition existed in the Android Binder IPC
subsystem in the Linux kernel, leading to a use-after-free vulnerability. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2022-20421)

David Leadbeater discovered that the netfilter IRC protocol tracking
implementation in the Linux Kernel incorrectly handled certain message
payloads in some situations. A remote attacker could possibly use this to
cause a denial of service or bypass firewall filtering. (CVE-2022-2663)

It was discovered that the Intel 740 frame buffer driver in the Linux
kernel contained a divide by zero vulnerability. A local attacker could use
this to cause a denial of service (system crash). (CVE-2022-3061)

It was discovered that the sound subsystem in the Linux kernel contained a
race condition in some situations. A local attacker could use this to cause
a denial of service (system crash). (CVE-2022-3303)

Gwnaun Jung discovered that the SFB packet scheduling implementation in the
Linux kernel contained a use-after-free vulnerability. A local attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2022-3586)

It was discovered that the NILFS2 file system implementation in the Linux
kernel did not properly deallocate memory in certain error conditions. An
attacker could use this to cause a denial of service (memory exhaustion).
(CVE-2022-3646)

Hyunwoo Kim discovered that an integer overflow vulnerability existed in
the PXA3xx graphics driver in the Linux kernel. A local attacker could
possibly use this to cause a denial of service (system crash).
(CVE-2022-39842)

It was discovered that a race condition existed in the EFI capsule loader
driver in the Linux kernel, leading to a use-after-free vulnerability. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2022-40307)

Zheng Wang and Zhuorao Yang discovered that the RealTek RTL8712U wireless
driver in the Linux kernel contained a use-after-free vulnerability. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2022-4095)

It was discovered that the USB monitoring (usbmon) component in the Linux
kernel did not properly set permissions on memory mapped in to user space
processes. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-43750)

Jann Horn discovered a race condition existed in the Linux kernel when
unmapping VMAs in certain situations, resulting in possible use-after-free
vulnerabilities. A local attacker could possibly use this to cause a denial
of service (system crash) or execute arbitrary code. (CVE-2022-39188)
