Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Memory leak (CVE-ID: CVE-2022-1012)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient randomization in the net/ipv4/tcp.c when calculating port offsets in Linux kernel cause by small table perturb size. A remote attacker can cause memory leak and gain access to sensitive information.
2) Information disclosure (CVE-ID: CVE-2022-0494)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output in the scsi_ioctl() function in drivers/scsi/scsi_ioctl.c in the Linux kernel. A local user with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) can gain unauthorized access to sensitive information on the system.
3) Use of insufficiently random values (CVE-ID: CVE-2022-32296)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to Linux kernel allowing TCP servers to identify clients by observing what source ports are used. A local user can gain unauthorized access to sensitive information on the system.
