SUSE CVE-2021-3573

A use-after-free in function hcisockboundioctl of the Linux kernel HCI subsystem was found in the way user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call hciunregisterdev together with one of the calls hcisockblacklistadd, hcisockblacklistdel, hcigetconninfo,...

Scientific Linux Security Update : kernel on SL7.x x86_64 (2022:0620)

The remote Scientific Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the SLSA-2022:0620-1 advisory. - kernel: use after free in eventpoll.c may lead to escalation of privilege CVE-2020-0466 - kernel: Use After Free in unixgc which could result i...

The vulnerability of the hci_sock_bound_ioctl() function in the HCI subsystem of the Linux operating system allows a attacker to execute arbitrary code in the kernel context.

The vulnerability of the hcisockboundioctl function in the HCI subsystem of the Linux operating system arises from the simultaneous execution using a shared resource with incorrect synchronization of the “race condition”. Exploiting this vulnerability allows an attacker to execute arbitrary code ...
