A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system.

AIX : Multiple Vulnerabilities (IJ37501)

The version of AIX installed on the remote host is prior to APAR IJ37501. It is, therefore, affected by multiple vulnerabilities as referenced in the IJ37501 advisory. - IBM AIX 7.1, 7.2, 7.3, and VIOS 3.1 could allow a non-privileged local user to exploit a vulnerability in the AIX kernel to cau...

CVE-2021-4090

An out-of-bounds OOB memory write flaw was found in the NFSD in the Linux kernel. Missing sanity may lead to a write beyond bmvalbmlen-1 in nfsd4decodebitmap4 in fs/nfsd/nfs4xdr.c. In this flaw, a local attacker with user privilege may gain access to out-of-bounds memory, leading to a system...

UBUNTU-CVE-2021-0076

Improper Validation of Specified Index, Position, or Offset in Input in firmware for some IntelR PROSet/Wireless Wi-Fi in multiple operating systems and some KillerTM Wi-Fi in Windows 10 and 11 may allow a privileged user to potentially enable denial of service via local access...

kernel: eBPF 32-bit source register truncation on div/mod

A flaw was found in the Linux kernel’s eBPF verification code, where the eBPF 32-bit div/mod source register truncation could lead to out-of-bounds reads and writes. By default, accessing the eBPF verifier is only possible to privileged users with CAPSYSADMIN. This flaw allows a local user who ca...

kernel: DoS in rb_per_cpu_empty()

A lack of CPU resources in the Linux kernel tracing module functionality was found in the way users use the trace ring buffer in specific way. Only privileged local users with CAPSYSADMIN capability could use this flaw to starve the resources causing denial of service...

PT-2021-7382 · Linux +5 · Linux Kernel +5

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 5.16 rc2 Description: A race condition was found in the Linux kernel's ebpf verifier between bpf map update elem and bpf map freeze due to a missing lock in kernel/bpf/syscall.c. This issue allows a local user...

A flaw was found in the Linux kernel. Improper input validation in some IntelR Graphics Drivers may allow a privileged user to potentially enable a denial of service via local access...

CVE-2020-24492

Insufficient access control in the firmware for the IntelR 722 Ethernet Controllers before version 1.5 may allow a privileged user to potentially enable a denial of service via local access...

UBUNTU-CVE-2020-12363

Improper input validation in some IntelR Graphics Drivers for Windows before version 26.20.100.7212 and before Linux kernel version 5.5 may allow a privileged user to potentially enable a denial of service via local access...

kernel: possible use-after-free due to a race condition in cdev_get of char_dev.c

A use-after-free flaw was found in the way the Linux kernel's filesystem subsystem handled a race condition in the chrdevopen function.
