Security Bulletin

This security bulletin contains information about 24 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU47103

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2020-0433

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local authenticated user to execute arbitrary code.

In blk_mq_queue_tag_busy_iter of blk-mq-tag.c, there is a possible use after free due to improper locking. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-151939299

Mitigation

Update the affected package the Linux Kernel to the latest version.

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

No. We are not aware of malware exploiting this vulnerability.

2) Cleartext transmission of sensitive information

EUVDB-ID: #VU52058

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2020-1749

CWE-ID: CWE-319 - Cleartext Transmission of Sensitive Information

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to incorrect implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted.

Mitigation

Update the affected package the Linux Kernel to the latest version.

3) Use-after-free

EUVDB-ID: #VU63652

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2020-25670

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error in the NFC LLCP protocol implementation. A local user can perform manipulation with an unknown input for the llcp_sock_bind() function to crash or escalate their privileges on the system.

Mitigation

Update the affected package the Linux Kernel to the latest version.

CVE-ID: CVE-2020-36322

CWE-ID: CWE-404 - Improper Resource Shutdown or Release

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists in the FUSE filesystem implementation in the Linux kernel due to fuse_do_getattr() calls make_bad_inode() in inappropriate situations. A local user can run a specially crafted program to trigger kernel crash.

Note, the vulnerability exists due to incomplete fix for #VU58207 (CVE-2021-28950).

Mitigation

Update the affected package the Linux Kernel to the latest version.

CVE-ID: CVE-2021-20219

CWE-ID: CWE-697 - Incorrect Comparison

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

A denial of service vulnerability was found in n_tty_receive_char_special in drivers/tty/n_tty.c of the Linux kernel. In this flaw a local attacker with a normal user privilege could delay the loop (due to a changing ldata->read_head, and a missing sanity check) and cause a threat to the system availability.

Mitigation

Update the affected package the Linux Kernel to the latest version.

CVE-ID: CVE-2021-27365

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error when processing Netlink messages in Linux kernel through 5.11.3, as certain iSCSI data structures do not have appropriate length constraints or checks, and can exceed the PAGE_SIZE value. A local unprivileged user can send a Netlink message that is associated with iSCSI, and has a length up to the maximum length of a Netlink message, trigger memory corruption and execute arbitrary code on the system with elevated privileges.

Mitigation

Update the affected package the Linux Kernel to the latest version.

CVE-ID: CVE-2021-28660

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a local user to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input in the "rtw_wx_set_scan" in drivers/staging/rtl8188eu/os_dep/ioctl_linux.c. A local user can trigger out-of-bounds write and execute arbitrary code on the target system.

Mitigation

Update the affected package the Linux Kernel to the latest version.
