CVE-ID: CVE-2021-43975
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the hw_atl_utils_fw_rpc_wait() function in drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c in Linux kernel.

EUVDB-ID: #VU61211
Risk: Low
CVSSv3.1: 3.3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-24448
CWE-ID:
CWE-909 - Missing initialization of resource
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to missing initialization of resource within the fs/nfs/dir.c in the Linux kernel. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor.
Update the affected package linux to the latest version.
