CVE-2020-26558

Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time.

Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time.

In smp_process_pairing_public_key of smp_act.cc, there is a possible interception of Bluetooth pairing from an on-path attacker due to improperly used crypto. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

• CVE-2021-33909: Extremely large seq buffer allocations in seq_file could lead to buffer underruns and code execution (bsc#1188062).
• CVE-2021-3609: A use-after-free in can/bcm could have led to privilege escalation (bsc#1187215).
• CVE-2021-33624: In kernel/bpf/verifier.c a branch can be mispredicted (e.g., because of type confusion) and consequently an unprivileged BPF program can read arbitrary memory locations via a side-channel attack, aka CID-9183671af6db (bnc#1187554).
• CVE-2021-0605: In pfkey_dump of af_key.c, there is a possible out-of-bounds read due to a missing bounds check. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation (bnc#1187601).
• CVE-2021-0512: In __hidinput_change_resolution_multipliers of hid-input.c, there is a possible out of bounds write due to a heap buffer overflow.

• CVE-2020-26558: Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time (bnc#1179610).
• CVE-2021-34693: net/can/bcm.c in the Linux kernel allowed local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized (bnc#1187452).

It was discovered that the BR/EDR pin-code pairing procedure in the Linux kernel was vulnerable to an impersonation attack. A physically proximate attacker could possibly use this to pair to a device without knowledge of the pin-code. (CVE-2020-26555)

It was discovered that the bluetooth subsystem in the Linux kernel did not properly perform access control. An authenticated attacker could possibly use this to expose sensitive information. (CVE-2020-26558, CVE-2021-0129)

It was discovered that the FUSE user space file system implementation in the Linux kernel did not properly handle bad inodes in some situations. A local attacker could possibly use this to cause a denial of service. (CVE-2020-36322)

It was discovered that the Infiniband RDMA userspace connection manager implementation in the Linux kernel contained a race condition leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possible execute arbitrary code. (CVE-2020-36385)

It was discovered that the DRM subsystem in the Linux kernel contained double-free vulnerabilities. A privileged attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-20292)

It was discovered that a race condition existed in the timer implementation in the Linux kernel. A privileged attacker could use…
