This security bulletin contains information about 6 secuirty vulnerabilities.


1) Improper Initialization (CVE-ID: CVE-2021-47261)

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

The vulnerability exists due to improper initialization within the destroy_cq_user(), create_cq_kernel() and resize_kernel() functions in drivers/infiniband/hw/mlx5/cq.c. A local user can perform a denial of service (DoS) attack.


2) Buffer overflow (CVE-ID: CVE-2021-47496)

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

The vulnerability exists due to memory corruption within the tls_err_abort(), tls_tx_records(), tls_push_record(), tls_sw_recvmsg() and tls_sw_splice_read() functions in net/tls/tls_sw.c. A local user can escalate privileges on the system.


3) Use-after-free (CVE-ID: CVE-2022-48792)

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

The vulnerability exists due to a use-after-free error within the mpi_ssp_completion() and mpi_sata_completion() functions in drivers/scsi/pm8001/pm80xx_hwi.c. A local user can escalate privileges on the system.


4) Use-after-free (CVE-ID: CVE-2022-48911)

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

The vulnerability exists due to a use-after-free error within the nf_queue_entry_dup() function in net/netfilter/nfnetlink_queue.c, within the nf_queue_entry_release_refs(), nf_queue_entry_get_refs() and __nf_queue() functions in net/netfilter/nf_queue.c. A local user can escalate privileges on the system.


5) Input validation error (CVE-ID: CVE-2024-46818)

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

The vulnerability exists due to improper input validation within the is_pin_busy(), set_pin_busy(), set_pin_free(), dal_gpio_service_lock() and dal_gpio_service_unlock() functions in drivers/gpu/drm/amd/display/dc/gpio/gpio_service.c. A local user can perform a denial of service (DoS) attack.


6) Memory leak (CVE-ID: CVE-2024-50302)

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

The vulnerability exists due to memory leak within the hid_alloc_report_buf() function in drivers/hid/hid-core.c. A local user can perform a denial of service (DoS) attack.

Note, the vulnerability is being actively exploited in the wild against Android devices.
