Linux Kernel could allow a remote attacker to bypass security restrictions, caused by a lockdown break issue. By sending a specially-crafted request using the kernel debugger, an attacker could exploit this vulnerability to perform read and write access to kernel memory.
Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by an invalid-free flaw in the io_uring subsystem. By executing a specially-crafted program, an authenticated attacker could exploit this vulnerability to gain elevated privileges or cause a denial of service condition.
Refer to Linux Kernel GIT Repository for patch, upgrade or suggested workaround information.
