The vulnerability exists due to a NULL pointer dereference error within the mlx5_get_uars_page() function in drivers/net/ethernet/mellanox/mlx5/core/steering/dr_domain.c. A local user can pass specially crafted data to the systen and perform a denial of service (DoS) attack.

Mitigation

Update the affected package the Linux Kernel to the latest version.

13) Race condition

EUVDB-ID: #VU75996

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-30772

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

The vulnerability allows an attacker to compromise the affected system.

The vulnerability exists due to a race condition in rivers/power/supply/da9150-charger.c in Linux kernel. An attacker with physical access to device can trigger a race condition while unplugin the device and execute arbitrary code on the system.

Mitigation

Update the affected package the Linux Kernel to the latest version.
