SUSE SLES15: kernel-azure / kernel-azure-devel / kernel-devel-azure / etc (SUSE-SU-2021:3640-1)

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3640-1 advisory. The SUSE Linux Enterprise 15 SP2 Azure kernel was updated to receive various security and bugfixes. The following security bugs were fixed: -...

kernel: slab out-of-bounds read in hci_extended_inquiry_result_evt() in net/bluetooth/hci_event.c

A flaw out of bounds memory access in the Linux kernel bluetooth subsystem was found in the way when some data being read about the bluetooth device with the hciextendedinquiryresultevt call. A local user could use this flaw to crash the system or read some data out of memory bounds that can lead...

kernel: locking inconsistency in drivers/tty/tty_io.c and drivers/tty/tty_jobctrl.c can lead to a read-after-free

A locking inconsistency issue was discovered in the tty subsystem of the Linux kernel. A local user could use this flaw to read numerical value from memory after free...

kernel: heap overflow in __cgroup_bpf_run_filter_getsockopt()

A flaw buffer overflow in the Linux kernel BPF subsystem was found in the way user running BPF script calling getsockopt. A local user could use this flaw to crash the system or possibly escalate their privileges on the system...

kernel: double free in bluetooth subsystem when the HCI device initialization fails

A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the system...

kernel: out-of-bounds reads in pinctrl subsystem.

A flaw was found in the Linux pinctrl system. It is possible to trigger an of bounds read due to a use after free. This could lead to local information disclosure with no additional execution privileges needed...

kernel: double free in bluetooth subsystem when the HCI device initialization fails

A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the system...

Denial Of Service (DoS)

linux kernal ipc is vulnerable to denial of service. The vulnerability exists due to a memory overflow in the memcg subsystem which allows a attacker to cause an application crash...

USN-5130-1 linux vulnerabilities

Jann Horn discovered a race condition in the tty subsystem of the Linux kernel in the locking for the TIOCSPGRP ioctl, 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-2020-29661 Jann Horn...

USN-5130-1: Linux kernel vulnerabilities

Jann Horn discovered a race condition in the tty subsystem of the Linux kernel in the locking for the TIOCSPGRP ioctl, 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-2020-29661 Jann Horn...

CVE-2021-21686

File path filters in the agent-to-controller security subsystem of Jenkins 2.318 and earlier, LTS 2.303.2 and earlier do not canonicalize paths, allowing operations to follow symbolic links to outside allowed directories...

kernel: out-of-bounds write due to a heap buffer overflow in __hidinput_change_resolution_multipliers() of hid-input.c

A flaw out of bounds memory write in the Linux kernel HID subsystem was found in the way user attach USB or other HID device that generates incorrect data inside HID report field. A local user could use this flaw to crash the system or possibly escalate their privileges on the system...
