EUVDB-ID: #VU63352
Risk: Low
CVSSv3.1: 5.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-20008
CWE-ID:
CWE-908 - Use of Uninitialized Resource
Exploit availability: No
DescriptionThe vulnerability allows a local application to bypass certain security restrictions.
The vulnerability exists due to usage of uninitialized resources within the mmc_blk_read_single() function in block.c. A local application can obtain potentially sensitive information from memory when reading from an SD card that triggers errors.
MitigationUpdate the affected package the Linux Kernel to the latest version.

EUVDB-ID: #VU66810
Risk: Low
CVSSv3.1: 5.8 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-2503
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to the way dm-verity is used to restrict module/firmware loads to trusted root filesystem in LoadPin builds. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates.
MitigationUpdate the affected package the Linux Kernel to the latest version.

CVE-ID: CVE-2022-3239
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the Linux kernel video4linux driver in the way user triggers em28xx_usb_probe() for the Empia 28xx based TV cards. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel to the latest version.

CVE-ID: CVE-2022-3303
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the Linux kernel sound subsystem due to improper locking when handling the SNDCTL_DSP_SYNC ioctl. A privileged local user can trigger a NULL pointer dereference error and perform a denial of service (DoS) attack.
MitigationUpdate the affected package the Linux Kernel to the latest version.

CWE-ID:
CWE-416 - Use After Free
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the dvb_demux_open() and dvb_dmxdev_release() function in drivers/media/dvb-core/dmxdev.c in Linux kernel. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

CVSSv3.1: 3.8 [CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-41848
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a race condition in the drivers/char/pcmcia/synclink_cs.c in the Linux kernel. An attacker with physical proximity to the affected system can remove a PCMCIA device while calling ioctl, cause a race condition between mgslpc_ioctl and mgslpc_detach and perform a denial of service (DoS) attack.
Update the affected package the Linux Kernel to the latest version.
