CVE-2021-34693

net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized.

net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized.

The Linux Kernel, the operating system core itself.

Security Fix(es):

there was a null pointer dereference in llcp_sock_getname in net/nfc/llcp_sock.c and reproduced it in linux-5.13.0-rc2. An unprivileged user can trigger this bug and cause denial of service. #Root Cause After creating an nfc socket, bind the address by calling bind(), if LLCP_SAP_MAX was used as SAP, it cause the bind() failed and there would set llcp_sock->service_name as NULL. Although bind() returns an error here, it does not affect calling other socket functions. sock_getname() would invoke llcp_sock_getname(), llcp_sock_getname copied service name from llcp_sock->service_name by memcpy but llcp_sock->service_name is NULL. #Fix the patch for this issue: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=4ac06a1e013c(CVE-2021-3587)

An issue was discovered in the Linux kernel before 5.10. drivers/infiniband/core/ucma.c has a use-after-free because the ctx is reached via the ctx_list in some ucma_migrate_id situations where ucma_close is called, aka CID-f5449e74802c.(CVE-2020-36385)

The vgacon subsystem in the Linux kernel before 5.8.10 mishandles software scrollback. There is a vgacon_scrolldelta out-of-bounds read, aka CID-973c096f6a85.(CVE-2020-28097)

In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, 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.(CVE-2021-33624)

kernel/module.c in the Linux kernel before 5.12.14 mishandles Signature Verification, aka CID-0c18f29aae7c. Without CONFIG_MODULE_SIG, verification that a kernel module is signed, for loading via init_module, does not occur for a module.sig_enforce=1 command-line argument.(CVE-2021-35039)

A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c. This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space(CVE-2021-22555)

A flaw use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in the way user detaches bluetooth dongle or other way triggers unregister bluetooth device event. A local user could use this flaw to crash the system or escalate their privileges on the system.(CVE-2021-3573)

Improper access control in BlueZ may allow an authenticated user to potentially enable information disclosure via adjacent access.(CVE-2021-0129)

net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized.(CVE-2021-34693)

An issue was discovered in the Linux kernel before 5.8.2. fs/io_uring.c has a use-after-free related to io_async_task_func and ctx reference holding, aka CID-6d816e088c35.(CVE-2020-36387)

A flaw was found in the CAN BCM networking protocol in the Linux kernel, where a local attacker can abuse a flaw in the CAN subsystem to corrupt memory, crash the system or escalate privileges.(CVE-2021-3609)

It was discovered that the eBPF implementation in the Linux kernel did not properly track bounds information for 32 bit registers when performing div and mod operations. A local attacker could use this to possibly execute arbitrary code.(CVE-2021-3600)

net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized.

This kernel-linus update is based on upstream 5.10.46 and fixes at least the following security issues:

• 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. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation (bnc#1187595).
• 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).

Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets (bnc#1185861).
• CVE-2021-33200: kernel/bpf/verifier.c enforced incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit (bnc#1186484).
• CVE-2021-33034: net/bluetooth/hci_event.c had a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value (bnc#1186111).
