The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the xgene_hwmon_remove() function in drivers/hwmon/xgene-hwmon.c in the Hardware Monitoring Linux Kernel Driver (xgene-hwmon). A local user can trigger a use-after-free error and execute arbitrary code on the system.

2) Use-after-free (CVE-ID: CVE-2023-1990)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error within the ndlc_remove() function in drivers/nfc/st-nci/ndlc.c. A local user can trigger a use-after-free error and perform a denial of service (DoS) attack.
