Description
This security bulletin contains information about 2 vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2019-10207)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local authenticated user to perform a denial of service (DoS) attack.
A flaw was found in the Linux kernel's Bluetooth implementation of UART, all versions kernel 3.x.x before 4.18.0 and kernel 5.x.x. An attacker with local access and write permissions to the Bluetooth hardware could use this flaw to issue a specially crafted ioctl function call and cause the system to crash.
2) Resource management error (CVE-ID: CVE-2019-13648)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a local attacker to perform a denial of service (DoS) attack.
The vulnerability exists in the "arch/powerpc/kernel/signal_32.c" and "arch/powerpc/kernel/signal_64.c" files on the PowerPC platform, when hardware transactional memory is disabled. A local authenticated attacker can make a "sigreturn()" system call that sends a signal frame that sends a signal frame that submits malicious input to the targeted system and cause a denial of service condition.
